RADIUM Engineering Fuel Pump Installation kit for BMW E46 M3 1999 – 2006 (No pump) – #20-0086 NEW PART NUMBER 20-0884

For those looking to increase the power output of their vehicle, this plug and play (bolt-in) fuel pump solution uses the most popular high performance 39mm diameter fuel pumps currently available on the market. 

This kit features a 6061-T6 CNC billet aluminum sleeve that slides over the corresponding 39mm pump to mimic the larger 43mm diameter BMW fuel pump. The machined “rib” locks and properly locates the filter sock in the BMW hanger assembly. The sleeve includes a laser etched logo. For protection, the sleeve is then anodized in order to resist alcohol (E85, ethanol, methanol) corrosion.

If you supply your own pump, measure the outside diameter of the pump body to ensure it is correct before ordering. The sleeve is designed for pumps with a 39mm diameter. If your pump is greater or less than 39mm, this sleeve may not work.

Also included are the necessary electrical components to make the kit plug and play (no cutting, drilling, grinding required). 

Not always necessary, but consider purchasing new Submersible Convoluted Fuel Flex Hose (see various lengths available) to replace the original which is commonly hard and brittle.
