alright, i am getting ready to seafoam my car this weekend. I am going to be putting a can in the gas tank, 1/2 a can in the crank case, and another 1/2 through the vacuum line. the problem is i don't know which vac line to use. can someone please show me a picture of which line to use. my car is a b6 05' a4 1.8t.

I plan to change my oil right after i seafoam with royal purple 10w40 full syn. and replace my bif oil filter of course. any help would be appreciated as usual.

You can use pretty much any vaccum line that goes to the manifold, the one right on front of the manifold is probably the easiest one to get at.
