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. No permanent modifications to the fuel system are required for installation of this product.
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). NOTE: The Walbro F90000262 Gas pump has the same connectors as the OEM BMW pump.
