Quantum Mustang 5.0 Fox Body EFI Fuel Pump Hotwire Upgrade Harness (Fuel Tank Bulkhead Pigtail Connector) 12ga 1986-1997

The Quantum fuel pump hotwire upgrade harness for 1986-1997 Mustangs and EFI fox bodies is designed to upgrade the factory bulkhead connector providing power to the intank pump. Over time, the copper strands in the already thin OEM harness tend to deteriorate, limiting clean voltage from reaching the pump, and preventing whichever pump is installed from functioning to its full potential. Fuel pump hotwire upgrades are a proven way of increasing a pump's output by as much as 20%. If you are installing a high volume, high output 255LPH, 340LPH, or 400/450LPH fuel pump into your Mustang (or EFI fox body), this harness should be considered not only as preventative maintenance, but also as must-have upgrade to allow the pump's to function to its full potential. The Quantum fuel pump hotwire harness uses thick 12 gauge wiring, and can be used with OEM hangers, as well as our QFS 8AN/6AN fuel pump hanger available separately.
