2004 Cavalier filling gas keeps popping the nozzle off

Hi all,

When attempting to fill up the wife's Cavalier, the nozzle keeps popping off. Can run maybe a gallon and half before the pressure relief pops. Turns out, this has been happening more and more often over the year. The car doesn't get driven much, maybe a Max of 3,000 miles a year for the past six years. Only about 115,000 total.

I've tried blowing a can of air down into the vent hose. Not much difference. During the next fill. Happens at different stations.

I found videos and articles online about this happening with other make/models, and it could be just a clogged vent tube or maybe worse, the evap canister.

Has anyone had this happen and is there anything I should look out for other than removing the vent tube and maybe the evap canister?
