One of the functions that the fuel pump fuse in a vehicle’s electrical system has is preventing too much current to go through to the fuel pump so it can work correctly. This is a 10-20 amp fuse that ensures that the fuel pump will get the right amount of electricity it needs to perform properly. When the current drawn by the pump is too great, this fuse will blow and protect the pump and other electrical components from damage.
The vehicle may have problems starting or can be stalled when the fuse breaks. That’s nearly 15 percent of the fuel system problems cited by drivers, according to information from the Automotive Service Association. Yep, it’s that simple — and without those checks many of your drivers will be stuck by the side of the road because they pay so little attention to it.
HOW TO CHECK FUEL PUMP FUSE: MOST EFFECTIVE WAYS2020 An open fuse box examination shows a blown fuse, typically marked by a broken wire in the fuse element. The fuse should only be replaced by the one rated to the original current rating; replacing with a too-high-rated fuse can create dangerous electrical problems, and potentially create fire.
Factory fuel pumps are rated at about 100k miles, but driving them on a blown fuse can decrease their lifespan. The fuse can end a nuisance, but further up in the electrical system there could be bigger problems — such as a failing fuel pump or faulty wiring. Mechanic Jane Doe warns, “A popped fuel pump fuse should not be ignored either; it could mean other things happening in the fuel delivery system.”
In short, the fuel pump fuse is designed to accomplish what a circuit breaker deigned to skip a beat on this system when over all electrical load necessary, and as such overheating.Go Back To Where The Fuel Pump Fuse Functions An Overload Protection Device.
