I heard that some have swapped in an later year single in-tank pump AND tank, lines, with harness, etc. into the dual pump model years.
Two electric pumps are used on fuel injected models; a low pressure boost pump mounted in the fuel tank and a high pressure pump mounted on the vehicle frame. The low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. The externally mounted high pressure pump is capable of supplying 15.9 gallons of fuel an hour. System pressure is at a working pressure of 39 psi, controlled by a pressure regulator mounted on the engine
If you need wiring diagrams, let us know.
