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.
