PCV Vacuum Line Size

[lovedores]

I ran 10mm outer* Hydraulic hose for my PCV/catch can setup. solid and works fine.

So the 10mm fits nice and snug over the thinner existing vacuum line?
The can I bought online doesn't indicate which is inlet and outlet, what's the best way to know?

If it does not say then I believe it does not matter which you use

Post a picture of the cab my man. As for the hose, I changed the plastic barbs in the manifold to brass 3/4 with a 1/4 thread. I’ll have to double check to make sure I’m right there. But if you keep the original plastic barbs, then I think the 10mm hydraulic hose is a bit big.
