Electric Fuel Pump: How to Do It Right However, if you don't have a way to automatically shut off your electric fuel pump you will keep spraying raw fuel all over your hot engine and wiring. Also, in a crash, your pump can continue to run feeding a fire if you don't have a way to stop it. Note: Never mount an electric fuel pump in an enclosed area such as the trunk or interior space... Electric Fuel Pump Wiring Diagram | GTSparkplugs 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.

How to rewire install fuel pump relay mod Enginebasics 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. Wiring in the Fuel Pump Relay . The relay should have 4 pins on it. They are usually labeled 30, 85, 86, and 87. Steps: 1. LS SWAPS: Fuel Systems Guide LS Engine DIY Electric fuel pumps require a lot of current, so it’s important to run a relay circuit from the pump trigger lead and to run 12 gauge positive and negative wires to the fuel pump. This ensures the pump gets the required amperage without over heating the wires. Do not run a 16 to 24 gauge primary wire to a fuel pump, because it will cause a fire. Wire gauge for fuel pump Pirate4x4. : 4x4 and Off ... I'm installing a new in tank fuel pump....aeromotive sealth 340.

(this is a generic statement based on average ampacity of wire size, look up the CORRECT amp rating for YOUR wire brand if you feel you are cutting it close) And fuse it to 20A ... FUEL PUMP CONTROL | FiTech Fuel Injection I know the wire size for the fuel pump circuit on my vehicle is probably no larger than 14 gauge. Aeromotive recommends running 10 gauge wire to the pump but that is to get full battery voltage current to the pump from an external relay. Fuel pump wire gauge 429 460 Re: Fuel pump wire gauge. BigDave65 wrote: best way to do it is to use a relay. As "BidDave" wrote, use a relay. As to the switch wires they can be small, 14 or 16 gauge.

Stealth 316 Fuel Pump Re Wire It is critically important that the fuel pump receive the maximum amount of voltage available from the charging and wiring system. The alternator will try to maintain about 13.5 volts into the system. Resistive losses along the current path to the pump will reduce the voltage at the pump to something less than 13.5. Holley 12 801 1 Fuel Pump Electric Installation Instructions 6. Connect one of the red wires to the positive wire (red wire) of the fuel pump. 7. Attach the in line fuse holder to the remaining red wire. After attaching the fuse holder, insert the 15A fuse and connect to the positive side of the battery. 8. Reconnect the battery cables. Figure 3 WIRING THE FUEL PUMP WITH A OIL PRESSURE SAFETY SWITCH: ELECTRIC FUEL PUMPS P N 12 801 1, 712 801 1, 12 802 1, 712 ... levels will be required for proper operation of the fuel system. WIRING THE FUEL PUMP: NOTE: A fuel pump can be wired as shown in Figure 4, but the preferred method is wiring it through a relay, as shown in Figure 5. 1. Disconnect the ground cable from the battery. 2. Connect the fuel pump (red lead) to a 12 volt ignition source.
