Gas nozzle clicking off

BEEFY

I Smile when Gasoline Can Freeze
This issue started on a trip over the summer but has gotten worse since then. When re fulling the gas nozzle kicks off constantly unless i fuel very slowly. Then after fueling it takes 2-3 cranks to start back up. Also the fuel tank seams to be creating a vacuum now. Would this be the evap purge valve causing this?

First Fill-Up (of many)
A friend of mine has the same issue with her 87 vandura. She has to tilt the nosel of the fuel pump a a certain angle or it clicks off. One difference is that hers drips gas if you fill it to fast. Could be an issue with the filler neck?
