FUEL FEED AND RETURN PIPES

The engine compartment connecting fuel pipe connects the chassis fuel pipe to the fuel rail assembly. The engine compartment fuel pipe is constructed of Teflon(R) with a braided stainless steel covering.

The chassis fuel pipe is located under the vehicle on the left side of the tunnel. The chassis fuel pipe connects the rear fuel feed pipe from the left fuel sender assembly to the engine compartment connecting fuel pipe. The chassis fuel pipe is constructed of aluminum with a plastic coating.

The rear fuel feed pipe connects the left fuel sender fuel pipe to the chassis fuel pipe. The rear fuel feed pipe is constructed of nylon with a covering of heat resistant rubber hose.

The auxiliary fuel feed pipes and the auxiliary fuel return pipes are located inside of the fuel crossover hose and inside of each fuel tank. The fuel pump supplies fuel through the auxiliary fuel feed pipe to the siphon jet pump inside the right fuel tank. The siphon jet pump transfers fuel from the right fuel tank to the left fuel tank through the auxiliary fuel return pipe. The return pipe feeds returning fuel from the right fuel tank directly into the left fuel sender reservoir. The auxiliary fuel feed and return pipes are constructed of nylon.
