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 GSS342 255lph and Walbro F90000267/274/285 variants. 

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. As shown, the adapter fittings can be changed for -AN style hoses as well (sold separately - contact us if this is required).

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

LATE MODEL NISSAN Fuel Hanger Surge Tank ADD-ON (20-0700) (20-0701)

This product is to be used with one of the fuel hangers above. 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.

As shown, simple plug and play connections are all that is required to attach the 2 systems together.

The surge tank can hold 1 or 2 aftermarket pumps including brushless variations. With the addition of the fuel pump in the OEM location, there could be 2-3 pumps inside the gas tank (total). Even with all of the extra fuel pumps, the FHST system is very straight forward and relatively simple to install.

No grinding, bending, or modification of the vehicle is required. Furthermore, the system is compatible with all alternative fuels such as E85 (when used in conjuction with Walbro F90000267/274/285 pumps.

 A Radium DIY wiring kit is required when running 2 surge pumps to wire in the second surge pump.

Other Information:

NOTES: 
1. Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
2. If it is important for fuel pressure to hold steady after the engine is shut down, install a check valve somewhere in the fuel system. 

3. External high current fuel pump wiring is provided for installing one FHST pump (1 relay, 1 fuse, and all associated wiring and hardware). To wire in a second FHST pump, a second fuse and relay are required. 4. Because the fuel pump supplying the FHST (in the original pump location) will now operate at very low pressure (high flow), the OEM external fuel pump wiring will be sufficient for this "lift" pump.
