The fuel pump relay is an important component of a car's fuel pump, which is an expensive device that functions well with the optimal amount of current. If the fuel pump receives excessive power, the wiring system around the pump can overheat, and the fuel pump could get damaged or fail completely. The fuel pump relay has a limited lifetime, so it should be checked regularly and replaced when faulty. The cost of replacing a fuel pump relay can vary depending on the year, make, and model of your vehicle, but the part itself typically costs less than $25, and a mechanic may charge a minimum of an hour's worth of labour to replace it.
