Just put the check valve in between the pcv and the intake and be done sir...And are you wanting to use those fuel lines?

 

I was planning on using the fuel lines since they are already there yes, and I know that is where the CV has to go, I am asking what fittings I would need to connect them securely to the fuel line, or if it would be easier to go with another kind of line and what to use then.

 

Use braided fuel line and -6 AN fittings

 

Alright I am not very knowledgeable about these types of fittings, what exactly would make it a -6? I assume it is something to do with size, assuming since it is -6 and I have a 3/8 check valve it means something like 6/16"? And how will I mount these fittings to the actual line? Is there some sort of crimping within the fittings?

 

The only thing AN sizing tells you is the outside diameter of the hose. The inside size will vary based on material, wall thickness and brand. -6 AN is 3/8 inch hose. There is absolutely no reason to waste money on braided hose for this application. You definitely want to use hose that will not collapse under heat and vacuum though.

 

just go to lowes and match the check valve with the fitting you need, i did the same thing, go to auto zone or advanced and get 3/8's fuel line, you need barb fittings for each side.
