Radium Engineering Dual Pump Add-On Mid 2003–2019 Corvette

Radium Engineering Dual Pump Add-On – 2003–2019 Corvette (C5/C6/C7)

Application: 2003–2019 Chevrolet Corvette (C5/C6/C7) | Part Number: 20-0937

The Radium Engineering 20-0937 Dual Pump Add-On is designed to work in conjunction with the Radium fuel hanger (part number 20-1010, sold separately). It provides a second independent fuel pump collector, enabling true dual-pump capability in the Corvette's uniquely shaped fuel tank.

Due to the small opening of the Corvette fuel tank, both pumps cannot be installed simultaneously. The Radium system solves this by sending each pump into the tank individually, using SAE quick connectors to simplify the installation process significantly.

Both fuel pump outlets merge into the single 10AN ORB outlet of the CNC-machined fuel hat. Check valves on each pump outlet permit fuel pump staging, allowing one pump to run at low load and the second to activate under high demand. All in-tank wiring is insulated with high-quality, chemically resistant ETFE for long-term durability.

NOTE: Part number 20-1010 must be purchased to use this add-on.
