need help FAST! with wierd tank issue
 

ok heres the deal I gotta sell my car to get a truck now. I know I know damn gas guzzler. I just started having a wierd issue with the gas tank and instead of playing dumb and selling as is I'd like to fix it.
the issue is I can olnly pump gas into it a few seconds at a time. I start pumping and then it stops like its full. I wait a few seconds and try again and it stops again, it even makes a sound like its full even when its almost empty? what is this? is there a vent thats blocked or something? help me quick please I gotta sell her.

There should be at least one more line that goes to the top of the filler neck. This would be a vent line. It may have a collapsed, pinched or blocked hose. I have heard of the foil caps from gas treatment bottles getting jammed in them and causing this issue.

thanks, how do I get to the vent? from the underside?

Not really sure. The fill tube and vent assembly should be all together and detachable from the body and the tank.
