Radium Nissan R32 GT-R Fuel Hanger Surge Tank Walbro or AEM 50-1200 - Pumps Not Included

The Radium Engineering FHST (fuel hanger surge tank) is the ultimate solution for fuel starvation issues. Fuel pump starvation is common when a vehicle is driven aggressively and fuel sloshes away from the in-tank fuel pump.

A stand-alone surge tank is an excellent device for eliminating fuel starvation, but installation can be complex. The FHST is a fully functional fuel surge tank contained inside the OEM fuel tank. It can be configured with 1, 2, or 3 high pressure pumps to feed fuel to the engine and 1 lift pump to keep the surge tank full. This system can meet the fuel demands of any engine power level for your R32 GT-R.

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 alternative fuels such as E85.

All kits come partially assembled with the final assembly performed by the technician during installation. There will be enough parts to run 1, 2, or 3 surge tank pumps and 1 lift pump. A lift pump is required in all installations.

The surge tank on this system is the collector box that is attached to the underside of the plate. It works by keeping fuel trapped around the pump (or pumps) that feed the engine. This ensures that fuel starvation will not occur and the supply of fuel to the engine will remain steady under all driving conditions.

The lift pump mounts in a stainless steel collector and scavenges fuel from the bottom of the tank to send to the surge tank. Fuel returning from the regulator also is routed into the surge tank, helping to keep it topped off.

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.

Because the required lift 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 the lift pump.

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 additional FHST pumps, extra fuses and relays are required. Consider purchasing Radium part number 17-0031 DIY Wiring Kit HERE for each additional pump.

The factory fuel level sensor is integrated into the OEM sender so a replacement fuel level sensor is provided. This new OEM Nissan sensor has the correct resistance range to work the gauge cluster properly. The original low fuel switch is reused.

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

PLUMBING

The preinstalled barb fittings permit direct connections to the factory rubber fuel hoses. No extra fuel plumbing is required.

8AN (feed) and 6AN (return) adapter fittings are provided for connecting aftermarket AN style hoses. The fitting ports are machined low enough to clear the unibody sheet metal.

(Clear fuel pump cover for the R32 can be found HERE).

NOTES

• Fuel pumps are sold separately
• At minimum, one lift pump and one surge pump is required to run this system
