I just used a crankcase breather. https://www.summitracing.com/parts/vpe-2167What filter did you put on it? It's funny I just replaced that plastic part.
I haven't had the charcoal canister hooked up for a long time. Which I think is also why that little valve thing didn't flow. I think it needs a vacuum on the line from the canister in order for it to open.
research paid off, I didn't need to modify my transmission crossmember, linkage or anything.
