I'm running a 7/32 vacuum line to my wastegate, and it's leaking because the fitting on my wastegate is too small. Will I be alright if I use a smaller vacuum line, or should I go out and buy a new fitting?

What is the best size for vacuum lines?

 

C'mon..

 

i would recommend to go with whatever size vacuum it fits on the fitting the wastegate came with.

 

The wastegate was used. What size fitting should I buy? What size vacuum line? Is bigger better?

 

i put an undersized vacuum line on my wastegate and it raised my boost to 11-12 psi (from 7-9)

 

Hm, interesting. What size vacuum lines does everyone run? (How many times will I ask this before getting an answer? )

 

I would like to know as well!
