I've been battling w/pressured gas cap/charcoal canister issues for years. I'd spray carb cleaner/pressurized air and get the check ball moving for a while, then it would seize up again and I'd swap the lines temporarily until I could get it moving again. Since OEM canisters are NLA I finally just replaced it with the Duralast VC120. Because of the limited ports (2 vs 3 on OEM) and the slightly larger size of the VC120 that makes fitting it in the OEM bracket a little tricky, there's a couple of tweaks required. There's different ways to do it, here's mine:
The purge line is 1/4", the tank line is 5/16", and the VCV is 3/8." I reduced the VCV from 3/8 to 5/16 w/a reducer, and then used a 5/16" T to tie the tank and VCV together. To make the new canister fit in the existing brackets I just used longer tightening bolts and drilled out the holes in the brackets that bolt to the frame so I could make the brackets a little wider. I'll clean up the OEM one and have it ready in case I need to swap back for smog check. Also replaced the fuel pump while I was in there, so let's pan out to that sexy new pump.
