Radium Engineering Fuel Hanger Surge Tank for Chevrolet Corvette C8 2020+ - Pumps Not Included

Radium Fuel Hanger Surge Tank, Chevrolet Corvette C8 (2020+) - Pumps Not Included

Application: Chevrolet Corvette C8 (2020+) – RH fuel tank
Part Type: In-tank fuel hanger surge tank (1-3 pumps)
Part Number: 20-1111

The Radium Fuel Hanger Surge Tank allows 1, 2 or 3 aftermarket fuel pumps to be run in the stock RH fuel tank of the 2020+ Corvette C8, installing on the side opposite the OEM pump module. The 20-1111 version suits the Ti Automotive E5LM brushless pump.

It can be configured three ways: as a true surge tank (direct injection only, or direct plus port injection), as a merged hanger for direct injection only, or as isolated direct and port injection systems. A venturi siphon jet pump draws fuel from outside the collector to the pump inlets (using 15-45 LPH depending on fuel pressure – allow for this when sizing pumps), while the one-piece anodised collector box is kept full by three 355 LPH one-way fill valves and fuel returning from the regulator. The 10AN ORB feed port has a low-profile 8AN male fitting, the return has a low-profile 6AN male fitting, and a 3/8in SAE quick connect is supplied for surge tank use.
