Have you heard of this Auto7 electric fuel pump ? I have not heard of it until I do a search on it...it is a necessary part of the fuel system that delivers fuel from the rear of the car where the tank is to the engine in the front. It does by pressurizing the fuel lines that run the length of the car . The pressureized fuel is then sprayed into the engine where it is burned. Wow ...now I know something about this auto fuel pump in the car :) I told Josh that he being a guy, he needs to know more the parts of a car !
