What is wiring diagram for electric fuel pump?
First some good practices, one is proper wiring, fusing and using the right safety circuits to keep you and your car safe. This project will show 2 basic wiring diagrams for electric fuel pumps. One without a warning light one with. Some parts are optional like the inertia switch, but highly recommended.
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.
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

What are the connectors for a fuel pump?
The connectors are two different sizes, for the larger wires for the ground and the supply for the fuel pump, and the smaller ones for the fuel stemming unit. Make sure you crimp them firmly, and make sure you don’t get any of the insulation trapped in between the electrical connective crimp.
Can a loose wire ignite a fuel pump?
Electricity should not be taken lightly. A spark from a loose wire can ignite fuel vapors resulting in a major catastrophe. Be careful. The first tip for wiring a fuel pump has to do with the electrical connections on the pump itself.
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.
How do you replace the harness on a fuel pump?
Start by disconnecting the battery first, and then disconnecting the wire harness from the fuel pump. Luckily for demonstration purposes, we have a harness that came off the vehicle.
Do you need to remove wire from fuel pump?
You’ll need to remove about a foot of the wire harness and the conduit from the old wire harness before you start cutting. Make sure you’re dealing with the one four wire connector for the fuel pump module, and not the fuel pump’s fuel pressure sensor connector.
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.

How do you re-wire a fuel pump?
The steps of re-wiring your fuel pump are to first get to your fuel pumps wiring. 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.
How big of a relay do you need for a fuel pump?
Choosing a Relay. The relay you need should be a four-prong relay with at least 14-gauge wiring. You do not want to get a relay that cannot handle the amperage that your fuel pump might pull causing the relay to fail, and you to be stranded on the side of the road.
