Car’s Fuel Pump

Knowing When to Replace Your Car’s Fuel Pump

by Radhe Gupta

Your car should always have the best parts to achieve peak performance when driving it on the road. There are many parts to take care of in a car, and one of the thousands of parts is the fuel pump. Note that you can never run your car without the fuel pump since it is responsible for sending fuel from the gas tank to the engine. 

If you own a car that has not been maintained for a long time, you should expect that most of its parts will need mending, especially the fuel pump. Once your car reaches 100,000 miles or more, the fuel pump will need replacing to ensure it runs correctly again. Before you look for parts like the walbro fuel pump, you have to know when is the right time to reinstate it. 

1. Stuttering Engine

The first sign that will tell you that you need a new fuel pump is when your engine starts sputtering when you floor the gas and hit top speed. The engine sputters because it lacks fuel sent to it, usually caused by a clogged or broken fuel pump. Not only do you have to replace the fuel pump, but your spark plug should be substituted. 

2. Low Fuel Pressure

If you are not sure whether your fuel pump needs to be changed, you need to drive over to a mechanic and have your car tested for its fuel pressure. The fuel pressure test will determine whether you need a new fuel pump or you can still drive it for a few miles. Usually, you can get a stock car’s recommended fuel pressure by checking the owner’s manual. 

You can also have one of your mechanic friends drop by your house and do the fuel pressure test yourselves. It is as simple as connecting the fuel pressure gauge tester on the engine and letting the other person rev the car. Once you notice that the gauge is not hitting the recommended fuel pressure, that is a clear sign you may need to look for reliable brands like the walbro fuel pump. 

3. Engine Overheat

You should also know that a failing fuel pump can stall your engine due to overheating. Even if you have an expensive radiator, your engine cannot run with a damaged fuel pump. You can usually notice if your fuel pump is causing the overheating by checking your radiator

Open the radiator cap and inspect if the water inside is scalding hot. When opening the radiator cap, a good tip is never to open right away because it will spit out super hot water that can cause severe burns. Let the engine sit and cool for an hour or two to ensure that you or no one else will get burnt. 

4. Surging Engine

If your engine stutters because of the lack of gas, you should also expect a broken fuel pump to send in more gas to the engine, which causes it to surge. It is one of the many dangerous problems that could happen to anyone because it makes your car unpredictable. A surging engine means that your car will suddenly pick up speed and then lose power quickly. 

Since you now know the common signs of fuel pump failure, you should have no problem replacing it and maintaining your car in top condition all the time.
