The fuel pump outlet is tapped for 8AN ORB (3/4"-16) female threads on the top plate. There are multiple adapter fittings included for the outlet.
1. The preinstalled -6AN male fitting permits an aftermarket feed line and/or connects to the plumbing kit listed below..
2. For other compatible adapter fittings, click HERE. 

The return inlet is tapped for 6AN ORB (9/16"-18) female threads on the top plate. There are multiple adapter fittings included for the return inlet.

FUEL PUMPS
Part numbers 20-2790 and 20-2792 are configured to be used with 1 aftermarket fuel pump.

NOTES:
1. If 2 aftermarket pumps are required, the supplementary "dual pump add-on" (20-2796 or 20-2797 listed below) is also required.
2. If installing a brushless pump, the "dual pump add-on" CANNOT be used due to the extra brushless controller wires.
3. Choosing the best fuel pump(s) is based on the expected engine power output, fuel type (gasoline, E85, etc.), and fuel pressure.

ELECTRICAL
The custom designed stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non-conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE. 

Notes
1. Single Walbro GSS342 (255LPH) fuel pump installations can re-use the OEM fuel pump wiring.
2. It is recommended to upgrade OEM wiring to ensure the pumps are receiving full power and operating at their full potential.
3. Universal fuel pump wiring kits can be found HERE. Select one for each aftermarket pump.
