Supercharge

Hey guys hope your all well. I just finish installing my sc on my 330ci and i have a concern about a "F" shape fitting that my manual doent tell me what to do. I think its the vacuum for the fuel regulator.

I believe the top is to the brake booster and bottom is to the fuel regulator? Not sure on a solution..

your kit should have come with a vacuum cap. Cap it off.

Really cap the brake booster ?

What would happen is that under load there would be less and less vacuum in the brake booster , sure not many people drive with a foot on the throttle and one on the brake but imagine something going bad in the throttle or something like that.

Pushing a rockhard pedal while your car accelerates is not something id like to do.

Better soloution is to plug them into the manifolds vacuum ports.
If fpr is to see constant pressure then sure cap it off

Just did an ESS kit the fuel pressure regulator line should go to the boost side of your intake not the vacuum side of your s/c. So your fuel pressure goes up when you are on boost. The brake booster needs vacuum, connect it to the vacuum side.

our cars are not meant to work well with a bov. with the maf sensor, your car will run super rich inbetween shifts. get a dv instead
