Good point. I didn’t think of that.

Still I think it’s a good idea to keep the separator’s flow restriction down. There’s a point where the restriction can get so high it doesn’t matter how much you pull vacuum...depends on how well the separator is designed. Some have really small nipples. That’s why I picked the BMW n54 style.
