Radium Dual Pump Add-On | 1993-1997 Honda Del Sol (20-3797 / 20-3796)

Two pumps in parallel, bolted to the hanger you already own.

The Radium Engineering dual pump add-on for the 1993-1997 Honda Del Sol adds a second fuel pump to an existing Radium Del Sol hanger, running both pumps in parallel for the flow a high horsepower build needs. It is an accessory to the hanger, not a standalone assembly.

Choose Your Version

• Fits Walbro GSS342 / AEM 50-1200 (20-3796): requires the 20-3790 hanger
• Fits Walbro F90000267 / 274 / 285 (20-3797): requires the 20-3792 hanger

What You'll Feel

• Double the delivery without replacing the hanger
• A staged path: one pump now, the second when the build demands it
• Components matched to your existing hanger and pump family

Features

• Everything needed to add a second pump to an existing Radium Del Sol hanger
• Pump-family specific, matched to the hanger version you own
• Runs both pumps in parallel

The Details

Match the add-on to the hanger rather than to the car: the 20-3796 pairs with the 20-3790, and the 20-3797 with the 20-3792. The hanger is required and is not included.

Neither add-on works with a brushless pump. The brushless controller wiring cannot fit through the hanger alongside a second pump, so a brushless Del Sol stays single pump. If you want two pumps, run conventional ones. Budget a Radium DIY wiring kit for the second pump, since the factory harness was never intended to feed two.

Kit Includes

• Components to install a second pump into an existing 20-3790 or 20-3792 hanger
• NOT included: the fuel pump, the hanger, and wiring kit

Applications

• 1993-1997 Honda Civic Del Sol fitted with a Radium 20-3790 or 20-3792 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
