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.

Also includes wiring connectors and hose clamps for a complete install. Instructions here.

For a complete pump setup, you will require:

• Radium Fuel Pump Connector Pigtails (17-0051-00)
• Radium Fuel Pump Inlet Filter Sock (14-0143)
• Walbro GSS342 High Pressure Fuel Pump (GSS342G3)
