When I'm at the gas station trying to put gas in my '68, the pump constantly shuts off. Even when I barely squeeze the handle, a little gas goes in then the pump does the automatic shutoff as if the tank's full.
I takes about 10 minutes to put any meaningful amount of fuel in the car, which is a pain because it gets about 8 miles per gallon! I checked and the filler neck doesn't seem to be blocked. I've had other '68s without this problem.
Pull the boot back away from the tank filler hole. It seals and the air being displaced by the gas in the tank comes back out and the pressure causes the pump to stop. Just a slight crack to relieve pressure makes all the differene in the world... If your using a nozzle without the boot try turning it 90 degrees from the way you would normally insert it!!
I always have better luck when I pull the pump almost all the way out of the filler neck as long as the pump doesn't have the gas recovery cup on it. As another poster stated I just pull the flexable cover back enough to allow air to flow when the pump does have one.
I should have mentioned that I have tried pulling the filler out almost all the way while filling, rotating it, etc. with no change. Most of the pumps around here don't have that rubber boot on the pump, but some do.
The tank has a small dent on the bottom, but it's very small. Any other ideas? Thanks.
That's funny....I have the opposite problem in my 67...the gas pumps never want to shut off until they spray gas all over the rear valence and bumper!!!! The pumps here do not have the vapor recovery boot.
Can you fit a hose into the filler tube? I had a Chrysler once that did this, and it turned out that someone had tried to steal my fuel and left the hose buried deep in the filler tube. I realized it was there after I myself tried to put a hose down the hole to see if it was clogged, and it wouldn't go in.

Same here. I have to get down and listen to the gas as it is filling. When I hear the sound change it is time to stop. And quick! Or else I am cleaning up the mess.
Hmmm... These filler tubes are just a straight pipe right, with no seperate vent or anything? Weird. My van is a bit stubborn when filling too, but it seems to have a vent to let the air out. It is kind of a 2 in 1 pipe, with the smaller filler tube inside of the larger vent tube. In your case, there may be some sort of vent elsewhere that is plugged and not letting the air out. I don't really know the details as I have never dropped a fuel tank before.
