Details

The GPA-Series Fuel Pump Module is designed to be used in many die-stamped alloy-coated and stainless steel gas tanks that have factory-installed reservoir trays. The tray is an absolute necessity for fuel-injection in order to prevent fuel starvation when accelerating and cornering.

The internal wiring harness, supply line, return line, filter sock and insulator sleeve are included. (The gasket and screws with o-rings are not included with the pump because they include gaskets and screws with our tanks.)

The heavy 10-gauge no-warp mounting plate contains fittings for the supply, the return, the vent and the electrical connector.  It is yellow-zinc plated to prevent corrosion.
