The Radium Engineering Fuel Pump Hanger is a complete drop-in replacement for the factory assembly, engineered to support the fuel demands of high-performance and high-power Nissan builds. Configurable with 1 or 2 aftermarket fuel pumps, it retains full factory functionality including the OEM level sender, low fuel switch, and fuel temperature sensor (OBD-II). Adapter fittings are included for all factory fuel line variations — no extra fuel plumbing required.

Radium Engineering has redesigned the venturi siphon system to eliminate the backpressure restriction caused by high-flow aftermarket pumps, while still effectively scavenging fuel from the passive side of the tank — just like factory.

Fuel Pump Compatibility

Kits come partially assembled — final assembly is performed during installation. Each kit includes enough parts to run 1 or 2 fuel pumps. Pumps must be supplied separately unless a “Pumps Included” option is selected.

Compatible fuel pumps:

• Walbro GSS342 255lph
• Walbro F90000267 E85
• Walbro F90000274 E85
• Walbro F90000285 E85
• Walbro F90000295 E85
• AEM 50-1200 E85
• Ti Automotive E5LM (brushless)

Note: When purchased with one pump included, additional parts are required to install a second pump.

• Stainless steel hardware and clamps
• Gasoline, methanol, and E85 compliant

Electrical

Custom-designed stainless steel electrical studs handle the high current demands of multi-pump and brushless setups. Connections are hermetically sealed and impervious to standard and exotic fuels. Non-conductive anodised aluminium acorn nuts prevent accidental short circuiting. In-tank wiring is insulated with chemically resistant PTFE.

Notes:

• Single pump installations can re-use OEM fuel pump controller wiring.
• Upgrading OEM wiring is recommended to ensure pumps receive full power.

FHST Add-On — Sold Separately (20-070X)

The Radium FHST (Fuel Hanger Surge Tank) add-on is the ultimate solution for fuel starvation in saddle-bag style OEM tanks common to late-model Nissans. It mounts a fully functional surge tank inside the OEM tank — eliminating fuel slosh and unstable pressure without complex external plumbing. Recommended to be used with a single pump hanger feeding the surge tank, which can then support one or two pumps to feed the engine.
