The filler tube either has a block in it or there is a major backflow issue. I cannot fully engage any gas station fill handle without it clicking and stopping the flow of gas into my tank. It is so bad I have to pull the gas pump nozzle almost completely out and trickle fill it like an old gas can.
There is a TSB on this but I am looking for an easy solution since I don't have the resources to get it fixed at a dealer. Jeep still hasn't issued a recall on this.

Good morning,

The TSB says it is a lifetime warranty extension which means it is a warranty repair for the line. That is assuming it is the line itself.

There is also the vent solenoid which is part of the canister assembly. If it is stuck closed, no air can bleed off for the fuel and this will result.
