Best Ways to Save Money By Learning to Keep Your Fuel Pump From Dying

How can you keep your fuel pump from dying? A typical fuel pump could last for the entire overall lifespan of your vehicle or at least 100,000 miles. This is something that you might notice when it comes to how to check fuel pressure levels as the pump may keep working.


But it is very easy for a fuel pump to wear out. So when you ask yourself, “What can I do to ensure that the pump keeps working?” This is important as the cost to replace a fuel pump can be at least $300 in most cases plus labor.

The points you will read about here entail how you can keep a proper mixture of air and fuel in your engine as the fuel pump works properly. When considered along other factors like how to test fuel injector functions, your vehicle’s throttle response and fuel economy will stay strong.

Knowing About the Fuel System


The fuel pump is one of the more essential parts of a vehicle to watch for. This is a part which delivers fuel into your engine. It pressurizes fuel from the gas tank and delivers it to the engine.

The fuel system has to be utilized with enough filters to keep the fuel pure while also having a fully functional pump so it can deliver the fuel the right way. A computer should especially use injectors that will move the fuel into multiple combustion chambers in the engine.

The pump will move fuel into your engine quickly. It can work for about 100,000 miles in most cases. Still, there are often times when you might notice that your system needs help.

Signs Your Pump Needs Help

The first point to consider when extending the life of your vehicle’s fuel pump is to ensure you take action as soon as possible. Your fuel pump might be in danger of wearing out or breaking down if it exhibits any of these signs:

  • Your engine starts to shut down when you put in more effort to accelerate.
  • Your engine sputters or jerks when you’re trying to go faster.
  • There could be sudden increases in speed when you are driving at the same consistent speed. This is due to the wear that your fuel pump has experienced over time.
  • Your vehicle might not start at all. This is due to the fuel pressure gauge not being able to identify the fuel in the tank, thus making it unable to actually deliver fuel to the engine.

Check to see that your fuel pump is working properly and that it is not at risk of any serious problems.

Why You Should Replace Your Fuel Filter


Like any filter, debris will clog it up over time. This causes the fuel pump to work harder, which can in turn lead to it breaking down. Engines can also be damaged from contaminated fuel.

As a result, you must regularly replace your inline fuel filter. This helps to keep your fuel system running smoothly.

The pump will typically collect particles and other impurities to keep the fuel clean as it gets to the engine. There is a risk for debris to build up over time, thus making it harder for your fuel pump to work smoothly. The excess fatigue will cause the filter to break down after a while.

You will have to regularly clean out the fuel filter in your vehicle for it to work properly. It should be replaced every year or after every 20,000 to 40,000 miles of use.


You must especially replace it regularly as you will risk pump failure if you replace a filter for the first time after 80,000 or more miles. The pump needs regular support through new filters. This comes as a pump that is far too used to having a clogged filter will not be able to handle the free flow of air and fuel.

You will have to ensure that all spots that you have filters in are cleared out properly though. The process of replacing filters will entail more than just getting rid of an old filter and adding a new one. You must also brush off the space that the filter is attached to and then check that the connections are securely fastened. Any bits of debris around the filter area should also be brushed off.

A fuel filter can cost around $100 to $150. This is for the part and labor.

Clean the Fuel Injection System


Next, you have to get your fuel injection system cleaned out regularly. This system works to move the fuel from the fuel pump into the engine. The fuel pump is typically attached to a relief valve and a fuel inlet. As fuel moves through the pump, it can get into many other parts including your injectors and a fuel pressure reader.

Get the fuel injection system cleaned out every 25,000 to 30,000 miles. This is to create a clear and healthy flow of fuel within your vehicle so it does not struggle to power up your car.

Avoid Cheap Additives

Many fuel additives are often poured into a fuel tank to make fuel work better. An anti-ethanol agent, as you will learn about later in this guide, can always work well as it ensures your fuel support continues to work well.

But that doesn’t mean you should not use just any additive. Some additives designed to support older vehicles or burning functions might feature corrosive chemicals.

These can hurt the fuel pump and other parts of your fuel system. As a result, you need to avoid anything that is cheap and may contain more dangerous compounds than necessary.

Keep Your Fuel Tank Filled Somewhat

When you keep it filled, the tank will feel cooler. This comes as it will not be going through far too much stress as it is cooled off. You must look at how well the tank is taken care of so it will not be any harder to handle than necessary.

The fuel works as a coolant for the tank and fuel pump. Therefore, the parts will not wear out or overheat. The fuel will cool off these parts and keep the pressure from the tank from being too hard to handle.

You must keep your fuel tank filled at least a quarter of the way filled and halfway filled during the winter. It might be harder for the pump to gather fuel from your tank if it is less than a quarter filled. The fuel will not be forced into the pump as well as it should. When the tank is filled, it will not be tough for it to take in the fuel you need.

In addition, the fuel pump will be slightly immersed when the fuel tank has enough fluid to work with. When the tank is mostly empty, it becomes harder for the pump to stay damp, thus making it a little hotter.

You must make sure that the fuel pump is properly cooled off and that it will not be at risk of any further harm. This is to ensure that the pump in question is strong and will continue to work well.

Naturally, you might think that you can hold off on filling your tank because you don’t think you will need to go too far with your vehicle after a while. You might also think that the cost of fuel will decline in your area. But the truth is that keeping the fuel tank close to empty will only cause your fuel pump to keep from working right.

Besides, you don’t want to worry about running out of fuel in the middle of the road to begin with. Therefore, it is a necessity for you to keep the fuel tank filled up the right way.

Use an Anti-Ethanol Agent

The last tip to keep your fuel pump healthy is applicable if you don’t burn fuel too often. If your vehicle has been idle for a week or two then you should add an anti-ethanol agent into your vehicle. A proper compound may be added into your fuel system to keep the fuel from gelling up.


This keeps it from being too hard for your vehicle to take in the fuel it requires. It is a necessity for when you’re using a vehicle with an engine that doesn’t have the ability to handle ethanol. While some vehicles can handle ethanol, that is clearly not the case for most vehicles.

But as mentioned earlier, you should still watch for how an additive is included. Be certain that you avoid using any anti-ethanol agents that are cheap and made with potentially corrosive materials. You should do your research to see which agents are safe for your specific vehicle while only using them when you actually have a need for doing so.

A Final Word!

The most important thing to do when taking care of your car is to ensure that you get its proper fuel injection features checked regularly. This is to ensure that your vehicle will continue to work for as long as possible. More importantly, you must get it checked early on in the event that any problems start to come about. The key is to see that whatever problems come about can be fixed before anything worse can come about.

For instance, you can use a fuel pressure tester to see if the pressure has been impacted to the point where your vehicle won’t work well. You can also check on your fuel injector to identify there are any individual ports that are not working out right. Whatever the case is, you should at least look carefully to see that your vehicle can be fixed up quickly.

Good luck with working on your vehicle’s fuel pump. You’ll find that it can last for as long as your vehicle can when you know how to make it work the right way.
