534-37 Dual Tank Fuel Pump Kit
Fuel Pump Kit for Holley 2 bbl TBI EFI systems up to 400 HP. This kit is designed to allow the use for all Holley MPI / TBI / Terminator EFI systems on vehicles equipped with dual fuel tanks. The fuel injection systems require a fuel return line. In dual tank applications, the fuel must be returned to the tank from which it was drawn. Originally designed for 2 bbl Pro-Jection PN 502-20S.. In addition to the items included in this kit, you will also need fuel hose, EFI pressure rated hose clamps, 18 gauge wire, 10 AMP inline fuse, assorted terminals, and assembly lube (Earl’s P/N 184004ERL or equivalent mineral oil that is compatible with your hose). The selection valve switches tanks by reversing the polarity of the “D” and “E” terminals. Many trucks equipped with dual tanks already have this type of selection valve along with the associated hardware.
