Hello all, I have a 2005 Tahoe Z71 with a 5.3l engine. Im currently having an issue when filling my gas tank. The nozzle keeps shutting off. So far Ive installed a new tank vent valve and charcoal canister, I removed the gas tank and blew out all the evap hoses that were on the tank, reinstalled the tank and attempted to fill up. It is still happening. Anyone else have this problem that could steer me in the right direction? Any help would be greatly appreciated. Thanks in advance.
