What kind of wiring do I need for a fuel pump?
Fuel pump wiring for the RED circuit is generally going to carry a much higher current than the relay. So use a larger gauge wire for lower voltage drop. For big pumps try 12 gauge, for smaller smaller 14 gauge.

What are the pins on a fuel pump relay?
The relay should have 4 pins on it. They are usually labeled 30, 85, 86, and 87. Steps: 1. Wire pin 85 of the relay to the 12v supply wire from the stock ECU that you just cut. This 12v wire will now energize the relay to turn on. So now instead of the stock ecu energizing the fuel pump, it will energize this relay. 2.
Is it safe to hook up an electric fuel pump?
Safe Electric Fuel Pump Wiring Wiring up an electric fuel pump is pretty simple, and taking a few extra precautions can make it much safer than just hooking it up to a manual switch or ignition circuit. Doing this properly in a race car is mandatory especially when some of these fuel pumps can drain a swimming pool in
Do you need to replace the wire harness on a fuel pump?
In this video we’ll show you how to replace the old fuel pump wire harness or pigtail with the new one that may be supplied with your kit. Wire harness is essential to make sure your new fuel pump will operate properly. We always put safety first, so make sure you wear your safety glasses and make sure you have a fire extinguisher on hand.
What kind of wiring do you need for a fuel pump?
At the wiring you need to find the 12v supply wire from the ECU to the fuel pump. Once that wire has been found cut that wire so that you now have half of that wiring running to the fuel pump, and the other half running to the factory ECU. Choosing a Relay The relayyou need should be a four-prong relay with at least 14-gauge wiring.

What’s the difference between black and purple fuel pump wire?
The black white wire is the ground for the pump. The purple is for the gauge on the dash and the black is ground for the sending unit. I don’t list a white wire being used. If the colors on the truck don’t match the tank, you’ll have to test them to verify each circuit.
What kind of wire to use for fuel pump?
Fuel pump wiring for the RED circuit is generally going to carry a much higher current than the relay. So use a larger gauge wire for lower voltage drop. For big pumps try 12 gauge, for smaller smaller 14 gauge. You want to limit voltage drop by using a heavy gauge wire.
