Happened 3x in last week at 3 different gas stations so it has to be the truck. Gas gauge is working. Gas pump keeps cutting off and can only get gas in if you hold to a trickle

    Hello Hossman, Bill from Milex Auto Repair. I would check the vent for the tank and make sure it's not pinched. Has any work been done at the tank recently , fuel pump ? If so possible it has been pinched when reinstalled. If not start with the vent hose first. Be happy to check it out for you if you don't find the solution.

    No work done on the tank. It got cold last weekend when it happened the 1st time. I've heard to put a bottle of STP dry gas in the tank and also to disconnect the vent and make sure there is nothing blocking it and/or drain out any gas that might be in the vent line. I'm pretty sure I'm getting the nozzle as far down the fill tube as I can. Thoughts?

    Try not to put the nozzle in so far, keep it out as close to the edge as possible.
    Also don't let the tank get down to empty, refill at 1/2 half a tank.

    I had the same problem. The repair shop replaced the vent hose (it was pinched) and that solved the problem.... for about 3 weeks. Now it won't fill correctly again. There must be something that is causing a vacuum and collapsing the hose. So far I have not found an answer to what would collapse the hose.
