Radium Fuel Hanger, Late Nissan, Pumps Not Included, Walbro GSS342 or AEM 50-1200

The Radium Engineering fuel pump hanger replaces the entire factory assembly. It can be configured with 1 or 2 aftermarket fuel pumps to meet the fuel demands of various high performance engines. Fuel pump options include Walbro (Ti Automotive) or AEM.
The functionality of the factory Nissan level sender, low fuel switch, and fuel temperature (OBD-II only) are retained. Adapter fittings are provided that permit direct connections for all factory fuel line variations (quick connect and hose barb). No extra fuel plumbing is required. The adapter fittings can be changed for -AN style hoses as well (sold separately).
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.

All kits come partially assembled with the final assembly performed by the technician during installation. Refer to the instructions for more details. The kit will have enough parts to run 1 or 2 fuel pumps and the user must supply their own compatible fuel pumps.

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. Enough studs are built in the top hat to accomodate brushless fuel pumps as well as the FHST add-on.
Electrical hardware is included for the fuel pump(s) and sensors. Furthermore, the in-tank wiring is insulated with high quality chemically resistant PTFE.

This product is to be used with one of the fuel hangers. It is recommended to use a single pump hanger to feed the surge tank. The surge tank can then be equipped with one or two fuel pumps to feed the engine.
The Radium Engineering FHST (fuel hanger surge tank) add-on is the ultimate solution for fuel starvation issues. Due to the saddle-bag style OEM fuel tank and insufficient baffling in late model Nissans, fuel slosh is common when driven aggressively. Unstable pressure resulting in a lean fuel mixture can cause engine damage. A stand-alone surge tank is an excellent device for eliminating fuel starvation issues, but installation can be complex. This add-on is a fully functional fuel surge tank mounted inside the OEM tank.
