Radium Fuel Pump Hanger for BMW E36

This Radium Engineering fuel hanger replaces both RH and LH fuel hat assemblies. It is compatible with 1 or 2 aftermarket fuel pumps. The kit reuses both passive side and active side fuel level sensors. It is also keeps a true saddle tank crossover system using new improved components. No cutting or modifying of the vehicle is required for installation.

FITTINGS

The merged fuel pump outlet is tapped for 10AN ORB (7/8"-14) female threads on the top plate. An SAE quick connecter barb is provided to connect to the OEM feed line. 

The fuel return inlet is tapped for 10AN ORB (7/8"-14) female threads on the top plate. An 8.5mm barbed adapter is provided to connect to the OEM return line.

All fittings are machined low enough to clear the surrounding area.

FUEL STARVATION PROTECTION

Several mechanisms work together to move fuel into the integrated collector and keep it full at all times. This ensures the pump(s) have adequate fuel available, even during aggressive driving. The integrated fuel tank collector is supplied with fuel from 3 different sources:

• The OEM collector bowl has a labyrinth. This keeps fuel from leaving the collector bowl when cornering.
• The constant low pressure returning fuel from the regulator activates the venturi jet pump siphon and also fills the collector bowl.
• The crossover fuel scavenged from the passive side of the tank from the venturi jet pump siphon is constantly filling the collector bowl.

PRV VENTURI JET PUMP

The OEM venturi jet pump is replaced with an innovative Radium Engineering variation. The venturi jet pump has a built-in pressure relief valve to control excessive fuel return flow. This is a common problem when using high flow pump(s) at low loads. This excessive pressure would pop-off the OEM venturi jet pump connection and prevent fuel transfer, ultimately leaving the vehicle stranded. The PRV venturi jet pump also permits low static fuel pressures.

ELECTRICAL

The custom designed stainless steel electrical studs easily handle the high current demand that compact multi-pin bulkhead connectors lack. They have an anti-rotation feature that prevents the terminals from spinning. 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. Furthermore, the in-tank wiring is insulated with high quality chemically resistant ETFE.

INSTALLATION NOTES

• Single pump installations can re-use the OEM fuel pump wiring.
• It is recommended to upgrade OEM wiring to ensure the single pump is receiving full power and operating at maximum potential.
• If using a second pump, a new dedicated relay and fuse pump MUST be used.
• Universal fuel pump wiring kits can be found HERE. Select one for each aftermarket pump.
