Radium Engineering Walbro GSS342 Fuel Pump Kit (E46 M3)


When looking to increase the horsepower of your E46 M3, the fuel pump can be the weak link especially when it’s already had thousands of miles of use. The problem when upgrading your fuel pump however, is that the BMW fuel pump has a 43mm outside diameter, whereas most aftermarket pumps are 39mm.

Radium’s fuel sleeve and install kits take this headache away and allow for the easy install of an upgraded pump. It comprises of a 6061-T6 CNC billet aluminium sleeve that slides over the new fuel pump and allows it to snap into place perfectly.

This listing is for a kit complete with Walbro GSS342 255l/h fuel pump, which is a perfect drop-in replacement for the original pump, which supports up to around 600bhp depending on application. Includes all parts needed for conversion, and filter sock. Instructions here.
