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.
