So I've finally got a code for my problem, and it's a vac leak like I kinda thought. Unscrew my gas cap, and it takes days for the tank to build pressure back up. I've already tried a new gas cap, and that didn't help at all. So maybe you guys have some tips for me. I've eyeballed all my vac lines that I could see, and they look sound, but I'm not really sure where to go from here.

TIA
Jeremy
