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

The Radium Engineering 20-1111 Fuel Hanger Surge Tank is designed for: 2020+ Chevrolet Corvette C8.

The Radium Engineering fuel pump hangers permits the use of 1, 2, or 3 aftermarket pumps in the stock RH C8 Corvette fuel tank. There are 3 common ways to configure this fuel system; Direction injection only, direct injection with port injection, and direct injection with port injection while using this hanger as a true surge tank. Furthermore, it is compatible with brushless fuel pumps. To simplifying aftermarket -AN hose plumbing, the 10AN ORB threaded feed port features a low profile 8AN male fitting and the 8AN ORB threaded return port features a low profile 6AN male fitting. A 3/8" SAE quick connect fitting is provided if using the hanger as a surge tank.

Notes

• The engine is commonly removed for accessing the fuel tanks.
• This fuel hanger seamlessly reuses the large EVAP connections.

Fuel Starvation

A siphon jet pump is integrated into the system. Using a venturi-effect, this "mechanical" pump draws fuel from outside the collector and distributes it directly to the pump inlets. It is driven by the energy built by the fuel pump(s) and only consumes 15-45 LPH of fuel flow, depending on fuel pressure. Take this fuel flow loss into consideration when sizing the fuel pump(s).

Several mechanisms work together to move fuel into the integrated collector and keep it full at all times. This ensures the pump(s) have adequate fuel available, even during aggressive driving. The integrated fuel tank collector is supplied with fuel from 3 different sources:

• The 1-piece anodized aluminum collector box keeps fuel trapped around the pump inlet(s).
• There are three 1-way fill valves incorporated in the bottom of the collector box that allows fuel in, but not out. Each 1-way fill valve flows 355 LPH.
• The collector box is constantly replenished with fuel returning from the pressure regulator.

Electrical

The custom designed anti-rotation stainless electrical studs easily handle the high current demand that compact bulkhead connectors lack. These serviceable connections are properly sealed and impervious to all standard and exotic fuels.

Nonconductive acorn nuts are provided to prevent any accidental short circuits. Furthermore, the high quality in-tank wiring is insulated with chemically resistant ETFE. Select qty1 for single pump applications, qty2 for dual pump applications, and qty3 for triple pump applications.
