87 TBI fuel pouring out of charcoal canister??? WTH

OK so I just got this truck. Its a 87 4.3 TBI. The guy I got it from said it would run good for a while and then start running bad and running rich. SO I started messing with it for a little while yesterday and it started pouring fuel out of the charcoal canister? Not just a little bit either. How in the hell can it be pushing raw fuel out of the vent like that??? I pulled the gas cap off and it released alot of pressure so I am guessing its building pressure some how. Anyways, I'm pretty good at this and I have no idea why its doing that.... Any ideas? Only thing I can think to do is, drop the tank this weekend and make sure any lines arnt crossed or pinched
