Description
Snow Performance Fuel Pump Relay Wiring Kit
Ensure maximum voltage supply and stable current delivery to high-output aftermarket fuel pumps with this complete heavy-duty relay harness kit.
High-Performance Fuel System Circuit Solution
Factory OEM fuel pump wiring is often lightweight and prone to significant voltage drops when powering high-flow aftermarket fuel pumps under heavy acceleration and high engine load. The Snow Performance Fuel Pump Relay Wiring Kit (SNF-20005) bypasses thin factory wiring by creating a direct, dedicated heavy-gauge power feed from your battery directly to your fuel pump.
Featuring a heavy-duty 40-amp relay and an inline 50-amp fuse assembly, this universal electrical kit safeguards your fuel system against voltage sags, ensuring your fuel pump operates at peak rated flow rate and fuel pressure when engine demands are highest. Perfect for high-horsepower road, track, and drag racing applications.
