This DIY wiring harness has everything you need to set up power for your fuel pump. Crafted with top-notch materials, it guarantees smooth operation and an easy install. Plus, its weather-sealed relay and fuse holder make it perfect for installing under the hood, where it might face the elements. This hardwire kit is far superior to models offered by other manufacturers currently in the field. Not all wiring is created equally. We use TXL wire featuring XLPE insulation that is heat, flame, gasoline, grease, and acid resistant and is used in extreme temperature applications of -40°F to 257°F!
