You don't have to be an expert to know what a fuel pump does; it pumps fuel. The fuel pump is vital to your engine operation delivering fuel from the tank to the engine. Failure of the pump will leave you stranded. A failing fuel pump can cause engine performance issues, stalling, sluggishness and even not starting at all. Other components can also cause these issues so if you are experiencing any of these have your car checked out by a professional. Your fuel pump is located in the fuel tank on most vehicles so many times tank removal is required to access the pump. One easy tip to extend fuel pump life is to keep your fuel tank at least 1/4 full. The fuel both cools and lubricates the pump. Excessive heat will shorten the life of the pump. Don't wait until the low fuel light comes on to refuel your ride.
