Suit 40mm Fuel Pumps with 2-Pin Delphi Plug.

Fuel pump wiring is one of the most neglected and misunderstood aspects of any performance fuel system upgrade. It's also one of the leading causes of fuel pump failure due to incorrect wiring.

This conversion wiring harness from Aeroflow Performance creates a simple and easy way to convert your factory OEM fuel pump to an aftermarket 40mm in tank fuel tank. One end features the Nissan OEM fuel pump 2 pin connector which should plug into the factory wiring harness.

The other end features a Delphi 2 Pin female connector which will plug into a 40mm fuel pump such as our 450LPH or 525LPH as well as popular brands like the Walbro pumps.

Made from 14 gauge wire with Viton heat shrink that accepts E85 and unleaded fuels. This wiring harness is designed to handle up 30 amps that these 40mm fuel pumps put out.
