Since my PCV hose ripped I plan on running a vacuum hose from both valve cover gaskets into the throttle. I hear some people saying its 3/8 and others 5/16's. Whats the correct size? Its the PCV hose that runs from back of driver side valve cover to the the pcv valve, and then into throttle.

Either will work ..but 3/8" is a better fit. The other is a Very tight fit. I used 3/8" as in my post.
