Fuel System Overview

The fuel tank stores the fuel supply. An electric fuel pump, located in the fuel tank with the fuel sender assembly, pumps fuel through an in-line fuel filter to the fuel rail assembly. The pump provides fuel at a higher pressure than is needed by the injectors. The fuel pressure regulator, pan of the fuel rail assembly, keeps the fuel available to the injectors at a regulated pressure. A separate pipe returns any unused fuel to the fuel tank.
