This Radium Engineering fuel hanger is compatible with 1 or 2 or 3 aftermarket fuel pumps. The kit reuses the OEM fuel level sensor as well as the OEM vent and ORVR emission ports.
There will be enough components included to use 1, 2, or 3 fuel pumps. Depending on the setup, some parts will simply not be used.
FITTINGS
The merged fuel pump outlet is tapped for 10AN ORB (7/8"-14) female threads on the top plate. However, a low profile 8AN male fitting is provided to connect to an aftermarket fuel line (not included). The fuel return inlet is tapped for 6AN ORB (9/16"-18) female threads on the top plate. A 6AN male adapter is provided to connect to an aftermarket fuel line (not included). All fittings are machined low enough to clear the surrounding area.
As shown, some vehicles (outside of the North America) do not have vent or ORVR ports. Note how the 2 ports on the OEM unit are sealed shut. For these applications, a 10AN ORB plug (shown red) and a 6AN ORB plug are included to seal these ports.
FUEL STARVATION PROTECTION
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 stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. They have an anti-rotation feature that prevents the terminals from spinning. These serviceable connections are hermetically sealed and impervious to all standard and exotic fuels. Non-conductive anodized aluminum acorn nuts are provided to prevent any accidental short circuiting. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE.
