Protec has developed a stage three anti surge kit for the E46 BMW M3. This simple kit allows you to cover the standard cradle inside the tank to stop the fuel escaping into the main tank thus leaving you with a full cradle and no fuel surge. Also it then allows you to upgrade the standard fuel pump to a brushless fuel pump giving you more flow for a lot less amps. This extra fuel flow means you can up the BHP of your car and feel safe in the knowledge you will not run out of fuel. Also we then change the standard fuel siphon system which is ran using the return line for a uprated pump module to make sure more fuel is moved to the drive side of the tank when on throttle. This is a common problem when running the siphon system on the return side due to when you are on throttle and there is very low reflow from the regulator. No fuel is being moved to the drive side of the tank means the cradle will empty fast and the pump will be starved of fuel.

It is easy to install and doesn’t require any modification to the standard system or fuel tank just remove your old parts and replace with the new parts supplied.

The kit comes with a cover plate (with the reservoir attached), a bung to close up the old transfer hose hole, SAE connector to place onto your standard transfer hose, a fully assembled drop in fuel pump module with pump (compact cobra 11904) and brushless fuel pump controller (16440) and a fully assembled passive side fuel module with hoses.
