Radium Dual Pump Add-On | 1990-2005 Acura NSX (20-2796 / 20-2797)

Two pumps, one hanger, without starting over.

The Radium Engineering dual pump add-on for the 1990-2005 Acura NSX adds a second fuel pump to an existing Radium NSX hanger. It supplies the components needed to run two pumps rather than one, so a build that started with a single pump can grow without replacing the hanger.

Choose Your Version

What You'll Feel

• Double the delivery without replacing the hanger you already own
• A staged upgrade path: one pump now, the second when power demands it
• Components matched to your existing hanger rather than adapted to it

Features

• Everything needed to add a second pump to an existing Radium NSX hanger
• Pump-family specific, matched to the hanger version you own
• Compatible with pumps of the same physical shape and electrical connector as the listed models

The Details

Match the add-on to the hanger, not to the car. The 20-2796 is a second pump kit for the 20-2790, and the 20-2797 is the equivalent for the 20-2792. The hanger itself is required and is not included, so this is an accessory rather than a standalone purchase.

Neither add-on works with a brushless pump. The extra brushless controller wiring cannot pass through the hanger alongside a second pump, so a brushless NSX build stays single pump. Two conventional pumps remain the route to higher delivery. Budget a Radium DIY wiring kit for the second pump, since factory wiring was never intended to feed two.

Kit Includes

• Components to install a second pump into an existing 20-2790 or 20-2792 hanger
• NOT included: the fuel pump, the hanger, and wiring kit

Applications

• 1990-2005 Acura NSX fitted with a Radium 20-2790 or 20-2792 fuel pump hanger

Important Notes

• The matching Radium hanger is required; this is an add-on, not a standalone kit
• NOT compatible with brushless pumps
