Radium Engineering Fuel Pump Install Kit | 2001-2006 BMW M3 (20-0884)

The S54 finally gets the pump the chassis's track habits demand.

The Radium Engineering Fuel Pump Install Kit for the BMW M3 upgrades the in-tank fuel pump on the 2001-2006 E46 M3: the mounting, adapter, and electrical hardware to install a modern high performance pump in the S54 car's factory hanger, feeding everything from bolt-on builds to the supercharger kits the platform loves. The M3's fuel system differs from the standard E46, which is why this kit exists separately from Radium's non-M version. Pump sold separately.

What You'll Feel

• Fuel delivery headroom for supercharged and built S54 engines
• A modern pump installed cleanly in the factory hanger, no improvisation
• Track-session confidence from delivery that matches the chassis's abilities

Features

• Fuel pump install kit for the 2001-2006 BMW E46 M3 (S54)
• Installs a high performance aftermarket pump in the factory hanger
• Mounting, adapter, and electrical components included

The Details

The E46 M3's saddle-style tank and S54-specific hanger separate it from the standard 3 Series, and Radium's kit resolves the fitment details an aftermarket pump needs on this specific architecture: inlet positioning, outlet interface, and electrical connection all differ from what the pump box assumes. Select a pump matched to the power target and fuel, upgrade the wiring with a Radium DIY kit if current demand warrants, and the S54's delivery stops being the limit. The non-M E46 uses Radium's separate 20-0894 kit; the two do not interchange.
