85 dodge pickup fuel problem (tank)

I was wondering if anyone had an idea for me...
I have a standard 2wd 318 d_150
I cannot add more than like 5 bucks in gas.
I think the vent is clogged but I dont know how to check. Can anyone help me out. I dont wanna try to take out the tank cuz i know the bolts are prob gonna snap and i dont think they are nuts and bolts.
please help [email protected]

the vent line runs out the top of the tank and then back to the fuel filter by the fuel pump. cut the end off and blow compressed air back and listen for gurgling in the tank, or air from the gas cap. watch out for fumes when you do it. if it's still clogged, you will have to lower the tank, or take the bed off, which may be easier. And, the bolts probably won't snap, if you clean off the road crud first! Try also filling the tank at a slower rate, or look for a restriction in the fuel fill hose, like somebody left part of a rag down there and it's still there...!
