Fig. 1: View of the fuel pump assembly and related components
The fuel pump is mounted to the fuel sender assembly inside the fuel
tank. The fuel is pumped to the engine at a specified flow and pressure
by the fuel pump. Excess fuel is returned to the fuel tank by the return
pipe. The fuel pump delivers a constant flow of fuel to the engine even
during low fuel conditions and aggressive vehicle maneuvers.
When working on or near the fuel tank, be sure to observe the
information molded on the bottom of the tank. Removal & Installation
Disconnect the negative battery cable.
Properly relieve the fuel system pressure.
