Review on Enhance Engine Performance with GM Genuine Parts 93441238 PCV Valve Hose by Darnell Murphy

I ordered it thinking it would fit my truck. It turns out that GM makes vacuum hoses in various lengths. Luckily in my situation all I needed was new rubbers on the ends and my old line was salvaged. I didn't even compare hose sizes, just thought the rubber fittings were rotatable. After basically skewing the leash they were attached to, I swapped out the fittings, tightened them up for extra confidence and everything fitted just fine! I would recommend using silicone grease or motor oil to make the installation process easier as the new ones are a lot stiffer than the old ones.
