Radium Engineering Dual Pump Add-On for Acura / Honda NSX 1990-2005 - Walbro F900

Radium Dual Pump Add-On, Acura / Honda NSX (1990-2005) - Walbro F900

Application: 1990-2005 Acura / Honda NSX
Part Type: Dual fuel pump add-on kit (Walbro F90000267/274/285)
Part Number: 20-2797

The Radium 20-2797 dual pump add-on installs a second Walbro F90000267/274/285 brushed pump in the Radium 20-2792 fuel pump hanger for the 1990-2005 Acura / Honda NSX. The 20-2792 hanger is required to use this add-on.

An electrical plug and an SAE quick connector remove the need for tedious assembly before the pumps go into the tank, and both pumps merge into the single 8AN ORB outlet of the fuel hat. The tank opening is small, so the two pumps cannot pass through at the same time – the second pump assembly goes into the tank first, followed by the first.

Key Features

• Second Pump: Adds a second brushed pump to the 20-2792 hanger
• Plug-In Connections: Electrical plug and SAE quick connector for easier installation
• Single Outlet: Both pumps merge into the hanger's single 8AN ORB outlet
• Staging: Pump staging is permitted with pumps that have integrated check valves

What's Included

• Stainless steel second pump (PUMP2) bracket and screws
• PUMP2 wire connector with red and black leads
• SAE quick connect fitting, convoluted tubing, EFI clamp and cable ties

Optional Parts

• Radium Engineering Hanger, 90-05 Honda NSX, (20-2792) – NSX hanger for Walbro F90000267/274/285/295 or brushless pumps
• Radium DIY Fuel Pump Hard Wiring Kit (17-0031) – one per aftermarket pump, with an independent relay and fuse, so each pump gets full current

Important Notes

• Requires the 20-2792 fuel pump hanger
• Compatible pumps: Walbro F90000267, F90000274, F90000285 and F90000295
• Not compatible with brushless pumps – a brushless pump limits the hanger to one pump
• Walbro F90000295 has no integrated check valve
• Dual pump installation is awkward in this tank because of the small opening
• Dual pump installations must use an independent relay and fuse – pump(s) are not included
• Installation instructions are available in the Instructions tab
