RADIUM Engineering 20-0937 Dual Pump Add-On Kit Mid 2003-2019 Corvette

The RADIUM Engineering 20-0937 Dual Pump Add-On Kit is designed to expand the fuel delivery capacity of mid-2003 through 2019 Chevrolet Corvette models by adding a second aftermarket fuel pump to the existing Radium in-tank fuel hanger system. This upgrade is essential for high-performance builds requiring increased fuel flow to support elevated power outputs.

Key Features:

• Includes independent fuel collector specifically designed for the second pump to prevent fuel starvation
• Features CNC-machined fuel hat with single 10AN ORB outlet where both pump outputs merge
• Innovative sequential installation design allowing pumps to enter the tank one at a time through the small factory opening
• SAE quick connectors simplify installation process significantly
• Check valves on pump outlets enable fuel pump staging capability
• High-quality chemically resistant ETFE-insulated in-tank wiring included
• Fuel pump filter socks included for both pumps
• Bolt-on stainless steel pump bracket for secure mounting
• Compatible with gasoline, methanol, and E85 fuel types
• Plug-and-play installation with drop-in design

Important Note: This is an add-on kit that requires RADIUM Engineering part number 20-0980 (C5/C6 fuel hanger) or 20-1010 (C7 fuel hanger) to be installed first. It cannot be used as a standalone product. Compatible with mid-2003 through 2019 Corvette models (vehicles manufactured after VIN 35114930, November 2002 production). Manual transmission applications only for 2003-2013 models.

The unique architecture of the Corvette fuel tank presents challenges for dual-pump installations due to the extremely small access opening. RADIUM Engineering's innovative design overcomes this limitation while maintaining proper fuel delivery, making it ideal for track use, forced induction, or other high-performance applications demanding maximum fuel capacity.
