as long as there is no air leak its all good, one of the npples is for the mfa. that is the fuel pressure switch as fitted to G60 engines, if you dont have a G60 dont worry about it!
Would the smaller nipple be for the MFA? and a clear plastic tube connect to it? because that was what was right next to it. I might get a new one just for the fact it would be nice for the MFA to work!
yeah you have a big chunky one which is capped off, and 2 small ones, one is capped the other goes to mfa
