I have an 04 Ram Hemi with 30k on it. The past 2 times I went to get gas the pump kept shutting off as if the tank was full. I took off the fill hose and it did not seem as if anything was obstructing. Any clue on how to remove the plastic vent line from the metal line? I was thinking of putting some air to it. Any other ideas?

 

Was it the same pump or station? I would guess a malfunctioning pump before doing anything to your truck. I've been to pumps before where they kept shutting off every few seconds.

 

Different gas stations. but thanks
