Wire Harnesses & Adapters - 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 310-320WHP range, 42#'s around 340-360. This kit increases those numbers by about 10%. This of course depends on the year of your car and many other factors but that gives you an idea of what to expect.

Further gains of about .4 volts can be had with our alternator rewire kit. We also have our alternator voltage booster for another .6 or 1.2 volts.

On the 2005 model GP, there is no fuel pump access panel. This kit will not install w/o dropping the tank. We recommend an alternative rewire method. This is not plug and play

Fuel pump rewiring kit

The directions were pretty thorough if I would have been working on a Pontiac lol! Was an easy installation after I looked up which wire to splice under the hood behind the fuse box. I used it for my 2004 Monte carlo ss. And on another note with the fuel door under the seat if you take a 1/4inch extension and a balpiene hammer instead of using players it worked much better. Just lay the door on top of the extension on a flat hard surface and using the ball side of the hammer lightly hit the door on either side worked real nice almost looked factory!

Fuel rewire

I just installed this yesterday i have a 2001 as monte carlo and the instructions are for a grand prix cousin's and damn near same car but they are not. Instructions are very vague and need to be vehicle specific and better pictures. Even though I knew what I was looking for I still do research to make sure since this my daily at the moment. I would have gave more stars but I will not when instructions are that bad. You can do a whole lot better. And include more videos of stuff on your your tube channels on the 3800 cars.
