The ZZP fuel pump rewire kit was designed to replace the anemic stock 18 gauge wiring. Most cars 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 powers the FP directly from the battery.
This kit upgrades your power and ground, look for 1-1.5 volt increase at the pump. It will not affect pump life and does not increase alternator load. Once installed it's totally hidden.
Real world testing shows pump volume increases of 10%. Stock fuel pumps (2006+) normally quit before hitting 400WHP with 60# injectors. This rewire gives you more headroom, especially in cars with larger injectors or raised fuel pressue.

Only ZZP brings you real world technical data to help you modify your vehicle to the fullest! Check out the fuel pump flow charge below to see how voltage can affect fuel pump flow.
The PCM commands duty cycle, it will never change unless you reprogram it.
The rewire increases fuel output from the pump but all of this is returned via FPR. That is unless FP is dropping due to low FP volume. That is where the rewire does it works. Keeping fuel pressure where it is supposed to be where normally it would fall w/o it.
Fits all LSJ and LNF applications.
