The five most common symptoms of a malfunctioning fuel pump include sputtering at high speeds, loss of power during acceleration, loss of power to the vehicle while under stress, surging, and an engine that will not start.

​

The maintenance and replacement of your vehicle's fuel pump is essential to the car's overall health. Your vehicle's fuel pump functions by transporting fuel from the fuel tank to the carburetor, according to the engine's requirements.

​

If you consistently drive your vehicle until the engine is almost out of gas, there is a high probability that your vehicle will eventually require a fuel pump replacement. Ideally, you should keep a quarter of a tank of gasoline in your vehicle at all times. When you let the fuel dip below this level, the fuel pump is forced to work harder and is more likely to fail.  However, the fuel pump will need to be replaced at some point, regardless of your driving habits. If your fuel pump fails to generate ample pressure within the fuel system it can cause the engine to lose power and not start.  You should have a GH Mobil mechanic give your car a comprehensive inspection to make sure your fuel pump is in working order.

Signs That You Need A Fuel Pump Replacement

If you notice that your check engine light is illuminated or there are sputtering noises coming from your engine, it is likely the pump needs to be replaced. Also, if you notice a significant change in your MPG it could be a sign of an issue with your fuel pump. You also may notice changes in power when your vehicle is on, such as changes in acceleration.  Most cars need fuel pressure at or above 50 psi in order to get your fuel injectors to fire.  Anything less than 50psi warrants a fuel pump and fuel filter replacement.
