I’m not sure why we need to go with stainless tubing on these, I used a piece of 3/8 copper soft I had around which bends up nicely with even a cheap Harbor Freight bender. I had my PCV located horizontal and lower (still 6-7” up from the engine), it did not draw oil but…it did have oil residue in it. Not to ignore HRL advice (never a good idea btw) I chose to relocate it to vertical and higher up. This install has a corvette v8 oil fill pipe with outlet, and a rubber 90 degree hose from NAPA. I took the air draw from the clean side of air filter to an oil filler cap and JB welded the valve slots.
