LOJ Conversions is now offering complete fuel system upgrades packages for the Infiniti G37 to make the existing returnless fuel systems in these cars compatible with the higher fuel pressure and flow requirements of the GM LS Engines.

The Radium Engineering FHST (fuel hanger surge tank) is the ultimate solution for fuel starvation issues in the Infiniti G37 chassis. Due to the saddle-bag style OEM fuel tank and insufficient baffling, fuel starvation is common when the vehicle is driven aggressively, such as on a track. This results in unstable fuel pressure and possible engine damage from running too lean. A stand-alone surge tank is an excellent device for eliminating fuel starvation issues. But installing a stand-alone FST is difficult in the 370Z due to the open-cabin design, and lack of a firewall between the driver and the rear of the vehicle. So Radium Engineering chose to create a fully functional fuel surge tank INSIDE the OEM tank.

The OEM fuel module must be upgraded to a pump with at least 340LPH (@ 40psi) rated flow in order for the venturi system to work correctly.

The Radium FHST can be used with 1 or 2 aftermarket pumps and supplies 1:1 regulated fuel to the engine. No grinding, bending, or modification of the vehicle's sheet metal is required. Furthermore the system is compatible with alternative fuels such as E85

- Drop-In Installation
- Permits 1 or 2 Surge Pumps
- Integrated 1:1 Adjustable Fuel Pressure Regulator
- Fuel Pressure Gauge
- Fuel Starvation Protection
- High Current Electrical Hardware
- Compatibility with Popular Fuel Pumps
- Anodized Aluminum Construction
- Gasoline, Methanol, and Ethanol Compliant
- Fuel Resistant Tubing and Wiring
- Stainless Steel Hardware

Brushed and brushless fuel pump options are available for the FHST. The system is suited, but not limited, to the following fuel pumps:

- Walbro GSS342 255lph
- AEM 50-1200 E85 340LPH


I was reminded this morning, two years after I bought my Z32 swap kit what a great company this is. LOJ is always there with excellent advice, not just great products. Best customer service of any company I’ve ever dealt with, and the highest quality swap parts available. If you want an easy, bolt in swap, this is it. Click Here to See Review
