    so we went to fill it up again on saturday and same problem with the pump clicking off.

    learn from my mistake and dont think you can just disconnect a few lines while the tank is lowered without disconnecting everything. just take it all the way out the first time and clean the hoses.

    wife and i did that sunday. dropped it out, blew out all the lines (and got a LOT of charcoal out again) until they were flowing substantial air out. reinstalled and it filled up like a dream.

    what an annoying problem.

    I have an 05 Cadillac Escalade. First issue I noticed was the pump stopping and not being able to fill the gas tank. Next I had the check engine light come on. I then replaced the purge valve and the evap canister. The check engine light went off, but the filling problem continued. I then got an alert on the display panel to tighten the fuel cap. I changed the canister solenoid next and I'm still having the issue. I have not actually checked the gas cap itself yet. From what I've read, I thought the problem would be one of the parts I've replaced but I haven't had any luck yet. Help please!!

    I've done the same thing as you with the same result at most pumps, however there are some pumps that I use that have no trouble filling up without clicking off. I've just chalked it up to a redesign in pumps over the last 13 years I've owned my truck.
