How Long Does It Take To Replace A Fuel Pump?

If your car is experiencing fuel delivery issues, you might be wondering, “how long does it take to replace a fuel pump?” A malfunctioning fuel pump can cause a variety of problems, from decreased fuel efficiency to stalling and failure to start. 

In this article, we’ll take a closer look at the fuel pump replacement process and explore factors that can affect how long it takes to complete the job. 

Whether you’re considering tackling the job yourself or bringing your car to a mechanic, understanding the timeline for this repair can help you plan accordingly.

About fuel pump

About fuel pump

Fuel pump is a component that any internal combustion engine vehicle has. Although not as large as many other components on the car, the role of this detail is extremely important. 

Because the fuel will not be able to move itself from the tank to the combustion chamber without the suction force generated by the fuel pump.


It is because of the necessity in the operation of the vehicle that manufacturers often try to increase the durability of this part. Thanks to that, the usage time of the fuel pump has increased a lot compared to the early period. However, after a fixed period of time, you should still check and replace the device to maintain working performance.

Location of fuel pump

Usually, you can easily find the fuel pump if you locate the tank. Because this detail will be located at the bottom or next to the fuel tank to facilitate the distribution of this important liquid. 

Some hybrid models or newer designs may have a more special fuel pump layout. That’s why you need to consult the information from the manufacturer before taking action.

How long does it take to replace a fuel pump

How long does it take to replace a fuel pump?

There will be no exact answer to the question how long does it take to replace a fuel pump because each vehicle will need different time periods to operate. You can base on the design and structure of the pump to make the most approximate judgments.

Typically, classic cars will need from 30 minutes to 1 hour to perform all operations from opening the bonnet to replacing the fuel pump and closing the system.

This number in modern vehicles will be from 3 to 6 hours of continuous work. Because the design and distribution of components in these products are extremely complex, the operation time also increases significantly.

All the above information is collected by me from professional craftsmen. In the case of self-manipulation at home, you will definitely need to spend more time to replace the fuel pump.

How much does it cost to change a fuel pump?

The average cost of a fuel pump replacement ranges from $100 to $600. The difference will come from two factors: the rarity of components and the responsiveness of the vehicle.


If you are using high-performance cars, antique cars or discontinued vehicles, finding replacement parts is quite difficult. So if you want to get a completely new fuel pump model, the cost will be extremely high. 

If looking for cheaper options, I think looking for used pump sets or a third-party product would be the best option.

Ability to meet

Many models today respond well to both prototype fuel pump models from automakers and similar equipment from accessory manufacturers. For this reason, you can easily make a choice to your liking. 

However, if you’re using too complicated media lines, you’ll need to find the right equipment to assemble it. And often the price of precision accessories is very high above $400.

Labor cost

So, how much to replace fuel pump? Not only the cost of parts but also the labor cost might be the important factor.

If we decide to take the car to the repair center, we will still need to spend between $120 and $300 more in labor costs. However, we can still negotiate to reduce the price to a level that we consider reasonable

What are the common symptoms of a failing fuel pump?

Signs of a bad fuel pump most prominent is a rapid performance deterioration in a short period of time. The main reason for this phenomenon comes from the fuel not being able to pump enough to the combustion chamber.

This situation will create many chain reactions and eventually cause a mismatch in the ratio of the fuel-air mixture. 

A mixture with an imperfect composition will not be able to generate enough energy to operate the vehicle stably.

In addition, you will also experience some other signs if the fuel pump on the vehicle is having problems.

The most obvious of which is the car stalling midway, having difficulty starting or having many problems when accelerating. Although the vehicle can be reactivated if you refuel but this is not a permanent method

In my opinion, failures with the fuel pump always cause many symptoms that negatively affect the performance of the vehicle and also the safety of us when traveling. 

So you need to quickly deal with these problems by replacing the pump as soon as possible.

What Are The Benefits of Fuel Pump Replacement?

Replacing a fuel pump can be a long and costly process. However, the benefits of this manipulation are also quite numerous and have a positive effect on many different aspects of the vehicle.

Restore performance

Only by replacing the fuel pump can we recover most of the performance loss caused by this problem. 

Through balancing the mixing ratio between air lice and fuel, the resulting mixture will eventually become stable. From there, the means can do work more efficiently.

Energy saving

If there is a problem with fuel transportation, this liquid will not be able to reach the combustion chamber in the usual way. The consequences of this phenomenon are not only negative effects on performance, but also the risk of fuel leakage. In addition, when there is a lack of traction, the engine tends to consume more gasoline or oil in an operating cycle.

Therefore, replacing the fuel pump can help the vehicle limit the risk of energy loss during operation.

Reduce gas emissions

Unbalanced air and fuel mixture will produce more CO2 and dust than usual. And it will be a disaster if we discharge these excess emissions directly into the environment for a long time.

If you want to do your part to protect the environment, you should not skip the fuel pump inspection and replacement. In addition, recognizing and limiting the bad gasoline is what we need to do. 

Engine protection

If you have to work for a long time in an overload condition due to lack of energy from a fuel leak or an imbalance of the fuel mixture, the engine will very quickly degrade. 

The only way that can help you maintain durability and protect the engine from dangerous hazards at this time can only be to replace a fuel pump.

Can a fuel pump be fixed and not replaced?

In most cases, you will need to completely replace the fuel pump if you want to stop the problems your vehicle is having. However, there will be a few cases where intervention is still possible through repair.

You will need to contact a repairer to find out what is the right method of action for you and your situation when to replace fuel pump. But for me, the replacement will always bring much more tangible benefits.

Is replacing a fuel pump hard?

Replacing any mechanism deep inside the system like the fuel pump has never been a simple task. Because we will need a lot of tools and knowledge to be able to handle most of the complex assembly stages.

Not to mention the risk of damage when you accidentally manipulate it wrong. With the parts related to the fuel tank, the risk factors are even higher because the risk of fire and explosion is very high.

So my advice is that you should not do this difficult process yourself here. 

Although in theory, anyone can manipulate with just a tool, but reality has proved the exact opposite. Only trained workers will be reputable enough to replace a fuel pump.

Can the mechanic encounter issues when replacing the fuel pump?

Mechanics can still make mistakes that lead to problems with the system in general and the fuel pump in particular. Although they have gone through the formal training process, nothing can guarantee their 100% success rate.

However, you should not worry too much about this. The difference between doing it yourself and taking the car to a mechanic isn’t in the success rate. Instead, the main problem will be that the experts will know how to fix the error that happened accidentally.

Meanwhile, we ordinary car users will not have enough tools and knowledge to quickly identify and fix the problem that is happening. And this delay will be the source of many dangers.


Is a fuel pump a major repair?

The answer is yes because although the fuel pump is only a small-sized part, the importance of this mechanism to the operation of the vehicle is extremely large. And all repairs directly related to vehicle performance will always be major repairs.

Do fuel pumps fail suddenly?

Fuel pump failures are usually sudden failures that occur during our move. However, the source of these problems comes from causes that occur during the move.

What does a failing fuel pump sound like?

The sound of a failing fuel pump failure is usually a very loud whine emanating suddenly in the fuel tank area of ​​the vehicle.

How do I know if my fuel pump has gone?

There are many signs for you to know if the fuel pump has gone, but the most noticeable is a clear decrease in performance after only a short time and the phenomenon of the car stopping midway and unable to move again. .

Can a fuel pump go out without warning?

Unlike other components, the fuel pump tends to stop working without generating any warning.


I hope that the knowledge in the article has helped you get the answer to the question, how long does it take to replace a fuel pump. This process is actually quite time consuming and complicated. 

So I hope that you will get the right decisions in the repair issue to maintain the stability of the vehicle.
