As of late, when I pump gas, I can only trikle the gas in, if that. It takes forever to fill the tank up. Does anyone know what could cause this?

Check the vent hose coming off the fuel tank and coming up to the filler neck. The hose could be restricted. The most probable cause I think would be the EVAP vent valve stuck closed or the EVAP canister restricted.
There was a GM bulletin a few years back pertaining to the fuel nozzles at stations causing this and nothing wrong with the vehicle. Have you changed stations recently or does it happen anywhere you fill up?

It happens at any gas station. What is the "EVAP" canister/valve and where is it located? Thanks

The canister and the vent valve should both be located underneath the truck by the fuel tank. look for the rubber hoses running from the fuel tank to the canister and electrical wiring to the valve's solenoid. The charcoal canister stores unburned fuel vapors from the fuel system and the vent valve vents those vapors to the engine or externally (fuel filler) depending on various factors. Hope this helps

you should also check to see if someone has tried to steal gas ther should be a preventing flap in the inlet tube to deter this problem
