Radium FUEL PUMP Install Kit E46 M3 WALBRO GSS342 255LPH PUMP INCLUDED 20-0082

For those looking to increase the power output of their 1999-2006 BMW E46 M3, this plug and play (bolt-in) fuel pump replacement solution uses the most popular high performance fuel pumps on the market.

This kit features a 6061-T6 CNC billet aluminum sleeve that slides over the corresponding 39mm aftermarket pump to mimic the larger 43mm diameter of the BMW fuel pump. The machined rib snaps into the fuel pump hanger and properly locates the filter sock. 

The sleeve is designed for 39mm diameter pump bodies. For pumps not listed above, measure the outside diameter to ensure it is correct before ordering. If the 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). No permanent modifications to the fuel system are required for installation of this product.

Not always necessary, but consider purchasing new Submersible Convoluted Fuel Tubing to replace the original which is commonly hard and brittle. Also, to fix the inherent fuel starvation issue found on the E46, we recommend using this product along with the Radium Fuel Surge Tank Kit
