The fuel pump is an integral part of the fuel system, literally pumping fuel from the gas tank into your engine. We recommend getting your fuel pump checked every 100,000 miles. However, if your vehicle loses power while accelerating, or if the engine sputters, chances are your fuel pump is not working correctly. Without a functioning fuel pump, your engine won’t receive the amount of fuel it needs and might not run at all. If the symptoms are ignored long enough, the fuel pump will eventually fail and need to be replaced. From a safety standpoint, there is a bit of a risk, because a failing fuel pump might cause you to stall unexpectedly. There is low environmental impact from fuel pump replacement.
