Fuel pump replacement Olathe KS

Fuel pump replacement service in Olathe KS by #CLIENTNAME

The job of the fuel pump is to transport fuel from your vehicle's gas tank to the engine. Fuel pumps are typically electrically powered and can be found inside or on the car's fuel tank. The ease and cost of fuel pump replacement is determined by the design of the vehicle. The decision to replace a fuel pump should be made only after it has been determined that the car's problem is not electrical or related to something else.

The most obvious sign that the fuel pump is not working is that the car will not start. This is not surprising if fuel is not getting to the engine. If you turn on the ignition and don't hear the pump motor activate inside the gas tank, the fuel pump is faulty. Another sign is loss of driving power on a regular basis, especially when accelerating or traveling at highway speeds. If the fuel pump seems to be working properly, the problem could be that the fuel pickup device in the fuel tank has become clogged and is no longer delivering enough gasoline.

With any luck, your pump will last the life of your vehicle. Fuel pumps are typically not a routine maintenance item, so they are replaced only when necessary. Some vehicle owners choose to replace as part of preventive maintenance, but there is usually no reason to do so until the pump shows signs of malfunction. Many cars have filters that can clog, so when a car is diagnosed with pump problems, the filter should be checked and, if necessary, replaced.

Don't risk being stranded if your car or truck won't start or hesitates when accelerating. Bring it to our L&D Auto Specialists shop for fast, affordable service.

How to disassemble and replace a fuel pump

The procedure for replacing a fuel pump will differ depending on the vehicle, but these basic steps are a good place to start.

First, check to see if your vehicle has an access panel that allows you to access the pump without having to remove the tank. If you need to loosen the tank, we'll show you how to do it.

First and foremost is safety.

We always prioritize safety, so be thorough and cautious. Wear safety glasses and gloves at all times. Leave plenty of room to work and have clean-up materials on hand to clean up any spills as soon as possible. It is recommended to work in a well-ventilated area, away from an open flame or anything that could cause a spark or ignite the fuel, such as pilot lights and incandescent bulbs. Keep a fire extinguisher handy at all times. Do not smoke. Always release fuel pressure before opening fuel systems, as releasing fuel while under pressure can cause fire and injury. Fuel must be stored in an approved container, such as a gas caddy or gas can.

How to replace the fuel pump

  • To begin with, you will need to jack up the vehicle so that the tank can be removed. If there is gasoline in the tank, you must first empty it into an approved container
  • During the repair, it is essential to clean the tank thoroughly
  • Next, when preparing to release the fuel tank, remove the clamps from the filler lines and then the filler lines. To prevent dirt from entering the tank, use a rag. While removing the clamps and carefully lowering the fuel tank, be sure to support it
  • Lowering the fuel tank carefully
  • Remove the straps carefully and lower the tank
  • Then disconnect the cable connectors and fuel lines that are connected to the module. Remove the pump retaining ring after cleaning the top of the tank
  • Remove the pump assembly so that it can be replaced with a new one. Note that some fuel pumps require removal of the parts from the old unit
  • Then simply reverse the procedure. Install the pump and pump retaining ring, then lift the tank close to the vehicle to reconnect the wire connectors and fuel lines. With the tank securely in place, reconnect the straps and fill lines. Partially fill the tank and start the vehicle to check for leaks
  • And you've got it. Just be cautious and adhere to safety precautions, and you'll be back on the road in no time. Replace the fuel filter as well to make sure your new pump runs smoothly

The primary function of a fuel pump is to deliver fuel from the storage tank to the engine, and it works with a variety of other car parts to do so. Unless you know the symptoms of a faulty fuel pump, it can be difficult to tell if it is failing.

The most important aspect of diagnosing a car is to listen and understand how it runs, operates and behaves on a daily basis. What kind of noises does it make? What makes it shudder? What are the typical RPMs? With this knowledge and an alert mindset, you will notice when the vehicle begins to run erratically.

Recognizing that the vehicle starts hard, has trouble idling or has less power is the first step in admitting there is a problem and trying to solve it. Since many parts of the car are interconnected and interdependent, diagnosing a problem is not always an easy task. It takes trial and error, and determining the exact source often requires the process of elimination.

That's what we're here to talk about when it comes to fuel pumps. Follow The L&D Auto Specialists's complete guide to the symptoms of a faulty fuel pump to find out what's wrong with your vehicle.

Fuel pump types

Automobiles have evolved primarily from mechanical pumps in the engine block in older vehicles to electric pumps inside the gas tank in modern vehicles. Below we will review the different types of pumps and how they work.

  • Mechanical fuel pumpA mechanical fuel pump employs positive displacement via a plunger or diaphragm. In a cyclic action, the pump sucks in fuel, traps it, then moves that fuel into the carburetor and engine, and the process repeats.
  • Electric fuel pump: The electronic fuel injection system in a modern vehicle requires higher pressure, which is achieved in part by using an electric fuel pump instead of a mechanical module.
  • In-tank: Most new vehicles sold today use fuel pumps housed inside the fuel tank. This protects the module, and the gas keeps it cool.
  • in-line pump: It is located between the fuel tank and the engine and is installed inside the fuel system track. It is much easier to replace than an in-tank pump. They are usually installed under the car or in the engine bay.
  • Rotary vane pumps: They use positive displacement to move fuel. A vane-type rotor operates off-center within a cavity inside a rotary vane pump. Being off-center, it creates a crescent-shaped space that allows fuel to enter. As the rotor moves, the vanes shut off a small amount of fuel and release it once it passes through the outlet valve. Vane pumps are classified into four types: rolling vane, sliding vane, flexible vane and oscillating vane.
  • Gerotor: A gerotor pump also uses positive displacement, but it does so in a different way. There are two intermeshing gears in a gerotor pump: a toothed inner gear and an outer ring gear with smooth curved lobes. The inner gear is positioned with respect to the outer gear. As a result, small pockets of fuel can be trapped, pressurized and released when rotating.

When should you replace your fuel pump?

There are several common signs that indicate a fuel pump problem. The most common symptom is engine sputtering when driving at high speeds, especially for an extended period of time. The car usually runs fine for about 10 minutes before the problem appears, and it will usually go away after a minute or two. The sputtering is due to the pump not providing a steady flow of fuel to the engine, which is usually a sign of low pump pressure.

Another common symptom is that the vehicle loses power when accelerating, which is similar to symptoms experienced when traveling at high speeds. Usually, the car will begin accelerating normally before jerking and sputtering, and then should resume its normal acceleration pattern. Again, lack of pressure at the pump means that the engine is not receiving the steady flow of fuel needed to accelerate.

A faulty fuel pump can also cause the vehicle to lose power when under pressure, such as when accelerating up a hill or towing a load behind. This is because the fuel pump cannot meet the increased demand for fuel, which can result in stuttering or loss of power. Another common symptom is that the engine fires without driver intervention, similar to when you press hard on the accelerator and unexpectedly propel the car forward. This is usually caused by a worn pump that is unable to draw the electricity needed to maintain a constant supply of fuel. Occasionally, it will increase pressure unexpectedly, causing the engine to overload.

The most serious symptom is that the vehicle will not start at all. If the above symptoms are ignored for a long period of time, the vehicle owner is likely to end up in this situation. When the pump fails completely, no fuel reaches the engine during ignition, resulting in the engine not starting at all.

What happens when a fuel pump is replaced?

  • The first step is to release the pressure in the fuel pump. Since turning off the engine does not release the pressure, it must be done manually before performing the repair.
  • To avoid sparking during the repair, the negative terminal of the battery must be removed.
  • There are two types of pumps: those that are installed inside the fuel tank and those that are mounted directly in front of it, under the car. This can be discovered by looking under the car or by following the fuel line from the tank to the pump.
  • To access the pump, the insulating sleeve must be removed. This should be loosened and dropped slightly before removing it.
  • After locating the pump, everything connected to the pump must be disconnected before it can be removed.
  • First, the fuel lines will be disconnected. There will be an inlet and outlet line, also known as low and high pressure ends. Before the lines can be disconnected, the hose clamp must be loosened and removed.
  • Finally, the fuel pump power leads must be disconnected. There will be two wires, one positive and one ground, that must be disconnected. These are usually held in place by small bolts or screws, and removing them should be a simple task.
  • Once everything is disconnected, the old pump can be removed. Everything will be reconnected after the new pump is installed. Once everything is connected, the mechanic will perform some tests to make sure everything is working properly.

How to save money when replacing a fuel pump

Most people should probably avoid trying to replace the fuel pump on their own. It's a difficult job, and it's an important part of the vehicle, so it's best left to a professional.

It pays to shop around for the best deal on repairs, as with most purchases. Get a few quotes from companies in your area, research the reputation of the ones with the best prices, and then make your decision. You should be able to get high-quality work at the lowest possible cost.

Fuel pump replacement tips to remember

First, don't jump to conclusions. Instead, perform a thorough diagnosis to make sure your fuel pump is faulty. Alternatively, have a professional perform the diagnosis for you. Because there are many other problems that can mimic a faulty fuel pump, you should obtain a complete diagnosis before proceeding.

If you determine that the fuel pump needs to be replaced, don't forget to replace the fuel filter at the same time. The filter on modern returnless fuel systems is integrated into the assembly, and is usually included with the new pump.

However, on older vehicles, a separate fuel filter may be installed in the line coming out of the tank. Filters of this type should be replaced at the same time as the pump to avoid contamination of the new unit.

Fuel pump replacement costs in Olathe KS by L&D Auto Specialists

It is not inexpensive to replace a fuel pump. The part itself can cost hundreds of dollars on modern vehicles that have an integrated fuel pump assembly.

Then there's the labor. Some cars (especially domestic ones) require the fuel tank to be removed to access the pump, which makes the job even more time-consuming. Other vehicles (usually imports) have an access cover under the rear seat, which makes the job much easier.

Because there are so many variables, the cost of fuel pump replacement varies greatly. If you have the work done by a professional repair shop, you should expect to pay between $1,000 and $2,000 for the job.

How much does it cost to replace a fuel pump?

It is determined by the type of vehicle you drive and the auto repair shop you visit. For a typical Toyota Corolla, the dealer price should be around $680. For more information, give us a call or drop by our shop for a quote.

Fuel pump replacement frequently asked questions

What exactly is a fuel pump and how does it work?

The fuel pump supplies gasoline under pressure to each of a car's fuel injectors. The fuel pump is located in the vehicle's fuel tank and is powered by a small electric motor. A regulator regulates the pressure and power of the pump. The fuel is filtered in the fuel tank with a collection screen or externally with a replaceable filter mounted in the fuel supply line.

When should you consider replacing your fuel pump?

A high quality OEM fuel pump can last indefinitely. A fuel pump, like any other electromechanical component, will eventually degrade and fail. It will need to be replaced if it fails to produce adequate pressure or stops working altogether. This failure condition is sometimes preceded or accompanied by one or more of the symptoms listed below:

  • The car will not start or stalls unexpectedly and will not restart. A faulty fuel pump may prevent the car from starting or cause it to stall.
  • The check engine light comes on. When a fuel pump gradually fails, fuel pressure and volume gradually degrade. Lack of fuel can cause the engine to run on an insufficient amount of fuel relative to the amount of air, causing the check engine light to come on.
  • The fuel tank makes a humming noise. When the fuel pump fails, you may hear a hissing or humming noise coming from the fuel tank area toward the rear of the vehicle. If the noise is coming from the fuel pump, failure is usually imminent, and you should replace the fuel pump as soon as possible.

How do mechanics change a fuel pump?

  • The fuel pump is checked to make sure it is not malfunctioning.
  • If the fuel pump fails, it is removed from the tank through an access panel located above the tank in the passenger compartment.
  • When there is no access panel, the fuel tank must be emptied and lowered from the vehicle to access the pump.
  • The fuel pump supply and return hoses, as well as the EVAP system hoses and electrical connections to the pump, must be removed in all cases.
  • Once the pump has been removed, the reusable brackets and collection screens are attached to the new pump before installation.
  • If the fuel system employs an external in-line filter, it is usual to replace the filter. All hoses and electrical connections are reconnected.
  • To check for leaks, fuel is added to the tank and the engine is started.

Is it safe to drive with a faulty fuel pump?

It is generally still safe to drive, but the pump could cause the engine and catalytic converter to overheat. A complete fuel pump failure can leave you stranded on the road, but many cars will not start after the initial drive.

However, if the fuel pump problem involves leaking gasoline or vapors, it is unsafe to drive and should be checked by a qualified mechanic immediately.

When replacing the fuel pump, keep the following in mind:

  • Before replacement, the mechanic will directly feed the fuel pump to ensure that the problem is a pump failure and not a faulty fuel pump power source.
  • Unless the fuel filter has been recently replaced, a new fuel filter should be installed whenever the fuel pump is replaced.
  • When the power supply fails sooner than expected, the power supply should be checked because a voltage drop in the fuel pump circuit can cause overheating.
  • If the fuel tank is lowered during repair, the fuel tank straps and fasteners should be inspected for excessive corrosion and replaced if necessary.
  • The fuel in the tank serves to cool and lubricate the fuel pump. To maximize the life of a new fuel pump, it is best to keep the fuel tank at least one-quarter full after installation.

What are the tools needed to install a fuel pump?

The tools needed to replace the fuel pump vary depending on the type of vehicle you own. However, in general, you will need

  • Protective eyewear
  • A fire extinguisher is a device that extinguishes fires.
  • Wheel support
  • A jack and a pair of jack stands
  • A ratchet, sockets of various sizes and wrenches of various sizes
  • A set of pliers and/or a tool to remove hose clamps (only required on some vehicles)
  • A tool to disconnect the fuel lines (only required on some vehicles).
  • To support the fuel tank, use a transmission jack or something similar (sometimes a regular jack and a block of wood can be substituted).

How long will the fuel pump replacement take?

The replacement of the fuel pump in the fuel tank and the in-line fuel filter, which must be replaced together with the fuel pump, will take 4 to 5 hours.

Is it easy to replace the fuel pump?

Do you have to do it yourself? Installing a fuel pump can be a challenge, especially if you have a full tank of gas. Also, since fuel is flammable, the task can be dangerous. If you decide to do it yourself, make sure you take all the necessary precautions and have a fire extinguisher on hand.

What are the symptoms of a faulty fuel pump?

The symptoms of a faulty fuel pump are:

  • The car won't start. There are a variety of problems that can prevent a car from starting, but one of the first things to look for is a lack of fuel.
  • Under a heavy load, a car shuts down
  • Unintended and inconsistent acceleration
  • Fuel efficiency has decreased
  • Engine temperature has increased
