Re: Tial 38 w/g vacuum line routing
On my old setup, I had the hole on the very top of it left open, and I used the one that was on the side. That was with my MBC.
When I switched to a Profec-b, I used the top port.
It was a long time ago so I don't remember the exact resoning, but that is what I was told was the correct way.
