Fitment Notes

• Verify OEM fuel pump diameter is 43mm before ordering - this kit is designed for 43mm OEM pump housings

• Fuel pump is NOT included - must be purchased separately
• If the pump does not include a filter sock, a compatible fuel pump filter sock must be sourced separately
• Aftermarket pumps may draw more current than OEM wiring supports - upgrade fuel pump wiring if the factory 15A fuse blows

Product Description

The Radium Engineering 20-0884 is a fuel pump install kit that allows the most popular 39mm aftermarket high-flow fuel pumps to drop directly into the factory BMW E46 M3 and E36 M3/3-Series (OBDII) fuel pump hanger - no drilling, cutting, or permanent modification required. The CNC billet 6061-T6 aluminum adapter sleeve slides over the 39mm pump body to match the OEM 43mm diameter, and the machined rib locks securely into the factory hanger while properly positioning the filter sock.

All necessary electrical components are included for a complete plug-and-play installation. Verify that your OEM pump is 43mm in diameter before ordering - if it measures 50mm, the non-M E46 kit (Radium 20-0894) is required instead. Fuel pump not included; a filter sock must also be present on the aftermarket pump or sourced separately.
