Radium Fuel Hanger Surge Tank, Chevrolet Corvette C8 (2020+) - Walbro F900
Application: Chevrolet Corvette C8 (2020+) - RH fuel tank
Part Type: In-tank fuel hanger surge tank (1-3 pumps)
Part Number: 20-1112
The Radium 20-1112 Fuel Hanger Surge Tank allows 1, 2 or 3 aftermarket fuel pumps to be run in the stock RH fuel tank of the 2020+ Chevrolet Corvette C8. It installs on the side opposite the OEM fuel pump module, which stays in place, and seamlessly reuses the large EVAP connections. This version suits Walbro F90000-series, Protec 11928, Fuelab 49614 and DeatschWerks DW810 pumps, and is compatible with brushless pumps.
There are three common ways to configure the system: direct injection only, direct injection with port injection, and direct plus port injection using the hanger as a true surge tank. A venturi siphon jet pump draws fuel from outside the collector to the pump inlets (consuming 15-45 LPH depending on fuel pressure - allow for this when sizing pumps), while the one-piece anodised aluminium 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 8AN ORB return port a low-profile 6AN male fitting, and a 3/8in SAE quick connect is supplied for surge tank use.
