I got a 2016 Chevy 1500 and I can’t get it to take any gas. After about a gallon or so it fills the neck up and it takes awhile for it to drain down. I replaced the solenoid vent valve and lines today , while doing that I took the line off the charcoal canister only to find that it was full of gas pulled it out and drained it blew it out with till dry put everything back together and still can’t pump any gas any ideals ?
