Radium FPR and Fuel Filter Kit, BMW E46 M3

Application: BMW E46 M3 (2001–2006)
Part Type: Fuel pressure regulator and fuel filter kit
Part Number: 20-0932-03, 20-0932-05

The Radium FPR and Fuel Filter Kit is a bolt-in kit for the 2001–2006 BMW E46 M3 that uses the factory fuel lines. The OEM fuel filter is replaced with a high-flow Radium fuel filter that installs into the OE mount, and the OEM regulator is replaced with a Radium Multi-Port fuel pressure regulator.

The RA-Series regulator adjusts without tools – no jam nut or set screw – with detents giving tactile feedback of about 1 psi per click. Its 360° swivelling, double O-ring sealed vacuum port takes four interchangeable #10-32 fittings. A fuel pressure gauge is included.

Key Features

• Bolt-In: Uses the factory fuel lines; filter installs into the OE mount

• Swivel Vacuum Port: 360° swivelling, double O-ring sealed, four interchangeable #10-32 fittings
• High-Flow Filter: Replaces the OEM fuel filter
• All Fuels: Gasoline (incl. leaded, oxygenated and pre-mix) and alcohol blends incl. methanol, ethanol and E85

Available Configurations

• 20-0932-03: 10 micron stainless filter element

What's Included

• Multi-port fuel pressure regulator
• High-flow fuel filter
• Fuel pressure gauge
• Necessary installation fittings

Important Notes

• Fuel pressure dropping quickly after shut-off is normal for aftermarket regulators and resets when the pump runs
• Long cranking or slow pressure build-up is not caused by the regulator – it points to fuel feed drain-back, usually an in-tank pump module leak (venturi jet pump or missing check valve)
• Installation instructions are available in the Instructions tab

Vehicle Fitment

• BMW E46 M3 (2001–2006)
