Radium Engineering Fuel Pump Hanger for Acura / Honda NSX 1990-2005 - Walbro GSS342 / AEM 50-1200

Radium Fuel Pump Hanger, Acura / Honda NSX (1990-2005) - Walbro GSS342 / AEM 50-1200

Application: 1990-2005 Acura / Honda NSX
Part Type: In-tank fuel pump hanger (Walbro GSS342 or AEM 50-1200 style pumps)
Part Number: 20-2790

The Radium 20-2790 fuel pump hanger for the 1990-2005 Acura / Honda NSX replaces the stock fuel pump assembly and suits Walbro GSS342 or AEM 50-1200 style pumps. No cutting or modifying of the sheet metal or fuel tank is required, and the pump sits in the factory collector bowl for fuel starvation protection.

All fittings are machined low enough to clear the factory sheet metal. The hanger is configured for one aftermarket pump; add the 20-2796 dual pump add-on to run a second pump. Custom anti-rotation stainless steel electrical studs handle the high current that compact multi-pin bulkhead connectors cannot, with non-conductive anodised aluminium acorn nuts and chemically resistant ETFE-insulated in-tank wiring.
