Radium Nissan S14/S15/R33/R34 Fuel Hanger For GSS342 Or AEM 50-1200 - Pumps Not Included

20-0630-00

The pre-installed adapter fittings permit direct connections for all factory fuel line variations (SAE quick connect and hose barb). No extra fuel plumbing is required if using stock fuel lines.

• The threads on the feed port are 10AN ORB (7/8"-14) female
• The threads on the return port are 8AN ORB (3/4"-16) female

If using aftermarket AN style hoses, low profile AN swivel adapter fittings will be required and are sold separately. Straight adapter fittings may also be used, but clearance with the access cover plate will not be possible. When installing aftermarket hoses, the crossover port and hose (center) does not need to be changed.

The OEM system uses a venturi jet pump to transfer fuel from the passive side of the tank to the active (pump) side of the tank. When using aftermarket high-flow pumps this venturi jet pump creates a restriction in the fuel return, resulting in unwanted backpressure and unmanageable fuel pressure. Radium Engineering has redesigned the siphon system to completely eliminate this restriction but still effectively scavenge fuel the same as factory.

ELECTRICAL

The custom designed anti-rotation 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. Enough studs are built in the top hat to accommodate brushless fuel pumps as well as the FHST add-on, described below.

Electrical hardware is included for the fuel pump(s) and sensors. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE.

NOTES

• Single fuel pump installations can re-use the OEM fuel pump controller wiring
• It is recommended to upgrade OEM wiring to ensure the pumps are receiving full power and operating at their full potential
• Universal fuel pump wiring kits can be found HERE. Select one for each aftermarket pump
• Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps
• If it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system.
