The Universal Fuel Pump Upgrade Wiring Loom is a purpose-built 80A hardwire kit designed to supply a clean, dedicated power source to your upgraded fuel pump.
Rather than running the high-current draw of a performance fuel pump through the factory harness, this kit routes power directly from the battery via a high-amperage relay �� protecting your factory wiring and ensuring your pump receives a full, stable voltage supply.
Factory fuel pump wiring is designed for the current draw of a standard pump. When a high-flow performance pump is installed, the factory circuit can become a bottleneck — causing voltage drop, heat buildup, and reduced pump performance.
- Prevents voltage drop to the fuel pump under load
- Reduces heat in the factory harness
- Ensures the pump operates at full rated capacity
- Required for most serious fuel system upgrades
- Eliminates risk of fire or harness damage from overcurrent
- 80A rated relay and wiring — handles the most demanding pump upgrades
- Dedicated switched power supply via relay — pump only draws power when ignition is on
- New connectors and terminals — no reusing old or corroded factory plugs
- Correctly sized and protected cabling — fused for safety
- Australian made by Greens Barra Solutions
Suitable for most vehicles running an upgraded inline or in-tank fuel pump, including:
- Barra engine conversions with upgraded fuel systems
- Turbocharged setups requiring high fuel flow
- Any build where the factory pump wiring is insufficient for the pump upgrade
