2011 yukon denali just started give me a hard time pumping the gas stopping every few seconds. I know it could be a clogged vent but I don't know where it is or how to get to it. I never looked under the truck so not sure what I'm looking at
If you have no codes.
The carbon canister took a shit and now you have carbon pellets plugging up the vent hoses. The canister sits right above the center of rear end, disconnect the hoses and drop the canister, if pellets fall out. Thats your problem.
To remove the pellets you need to remove the gas tank and blow them out.
