Being that old, I am Guessing the fuel tank has been removed to replace the fuel pump and the gas tank vent hose was not connected properly or has a smash in it, or not connected, when put back up which will cause the hard to fill up problem as it can not vent the fumes fast enough. Fumes may leak under, then inside the car instead of to the filler neck that goes to the outside of the car. I had that happen. Crawl under, look and feel around to check this.

Does it only do this when you have a full or near full tank? The O-ring on the fuel pump can crack over time which will do this when the tank is full or nearly full. You have a bad gasket or O-ring somewhere for sure.
sounds like the pump handle is clicking off ?? yes ? -- if this is the case - try and fill slower and/or don't insert the pump pipe all the way in ( like don't cram it in there )-- back it out some.
Chrysler and Dodge have a fuel vapor filter that allows air out of the gas tank but filters the harmful fumes. Usually the problem happens from topping off your gas after the gas pump stops due to the automatic shut off and then putting more gas in the tank (to make the bill an even $50. or to the next $5 increment, or pumping more in just because it fits). Anyway the filter gets saturated with gas, is not able to breath, and causes a vacuum in the tank. Because of this, the anti-siphon ball is not able to float around and sits at the opening of the fuel fill tube and won't allow any more gas to be put in (acts like the car is full). If you pump super duper slow like put a nickel to hold the gas pump handle, it will trickle in without a problem, but it takes forever! Solution, get the filter replaced and don't over fill the tank.
don't over fill the tank, when it clicks off thats it!! any check engine light? I had fuel smell, and the O-Ring was leaking when I changed the fuel pump. Top of the fuel tank, was leaking only on a full tank, Also evap, pump and hoses do crack and leak but it will show, in a check engine light usually
yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.
