3800 Fuel Pump Rewire Kit

The ZZP fuel pump rewire kit was designed to replace the anemic stock 18 gauge wiring. Most GTPs are losing between 1.5 and 2 volts to the stock pump because of line losses in the wiring. Since our fuel pumps are positive displacement rollervane pumps, this matters A LOT! Flow is directly proportional to fuel pump speed which is directly proportional to applied fuel pump voltage. Upgrading your fuel pump wiring will give you quite a bit more headroom with your stock pump. Our rewire kit runs a new wire all the way from the fuel pump to the factory relay.   This kit upgrades your power and ground, look for 1-1.5 volt increase at the pump. Uses factory connector so there is no need to cut wires at the pump. It will not affect pump life and does not increase alternator load. Once installed it's totally hidden. No worries about taking your car to the dealer for warranty work.   Real world testing shows increases of 2-3 psi max fuel pressure. Stock injectors usually fall off in the 310-320W
