Hi all,
I recently installed the IE short runner intake manifold and a generic non baffled catch can(I know, but it was free). And I was having some issue where I turned out to have the wrong tubing which would collapse under vacuum. I now have fuel line of the OE pcv size, stepped down to about 5/8" iirc into the catch can, then same size out, stepped down to one of the smaller IE manifold vacuum ports. So, my question is, is there a size hose I should be keeping the vacuum Lines at? Or is stepping it down as needed ok as long as it's holding vacuum? Also have new valve cover and gasket for unrelated reason so it's also a new pcv.
Thanks in Advance for input.
