This Radium Engineering fuel hanger replaces the stock fuel pump assembly. No cutting or modifying of the vehicle is required for installation. A second pump add-on option is available and sold separately. Plumbing kits are available to simplify the installation process and provide high flow fuel lines and fittings.
If 2 aftermarket pumps are required, the dual pump add-on listed below must also be purchased. Choosing the best fuel pump is based on the expected engine power output, fuel type (gasoline, E85, etc.), and fuel pressure.
FITTINGS
- The fuel pump outlet is tapped for 10AN ORB (7/8"-14) female threads on the top plate.
- The included fuel pump outlet fitting is 8AN male.
- The fuel return inlet is tapped for 8AN ORB (3/4"-16) female threads on the top plate.
- The included fuel return inlet fitting is 6AN male.
All fittings are machined low enough to clear the surrounding area.
PREVENTING FUEL STARVATION
Several mechanisms work together to move fuel into the integrated collector and keep it full at all times. This ensures the pump has adequate fuel available, even during aggressive driving. The internal pump is supplied with fuel from 3 different sources:
- The consistent crossover fuel scavenged from the passive side of the fuel tank.
- The constant low pressure returning fuel from the fuel pressure regulator.
- Two 1-way fill valves on the bottom of the collector allow fuel in, but not out. Each valve flows 355LPH keeping the collector as full as the current fuel tank level.
ELECTRICAL
The custom designed stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. 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.
