Description: Radium Engineering Fuel Pump Hanger

Details:

COMPATIBILITY
90-05 Acura NSX (All models/trims/RHD/LHD) 

OVERVIEW
This Radium Engineering fuel hanger replaces the stock fuel pump assembly. No cutting or modifying of the vehicle's sheet metal or fuel tank is required for installation.

The fuel pump is positioned in the factory collector bowl for fuel starvation protection. 

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.
1. The preinstalled -6AN male fitting permits an aftermarket return line and/or connects to the plumbing kit listed below..
2. For other compatible adapter fittings, click HERE.

All fittings are machined low enough to clear the factory sheet metal.

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.

DUAL PUMP ADD-ON
Part numbers 20-2796 and 20-2797 are supplementary add-ons to the fuel pump hanger discussed above.

NOTES:
1. Part number 20-2790 or 20-2792 are required to use these add-ons.
2. If a brushless pump was installed, a "dual pump add-on" CANNOT be used due to the extra brushless controller wires. 

The architecture of this fuel tank is very unique. Because the opening is so small, 2 pumps cannot fit through at the same time. 

The pump 2 assembly is placed in the tank first followed by the pump 1 assembly. An electrical plug and a SAE quick connector eliminate the need to perform tedious assembly before dropping the entire assembly into the tank. Both fuel pumps merge into the single 8AN ORB outlet of the fuel hat. And because of the integrated check valves, fuel pump staging is permitted. 

FUEL PUMPS
Choosing the best fuel pump is based on the expected engine power output, fuel type (gasoline, E85, etc.), and fuel pressure.
