Gas pump keeps stopping when I fuel up.

[Chvytahoe11]

Got my waterpump issue taken care of, now i want to fix this annoying issue when i fuel up my tahoe. Gas pump keeps stopping often, takes about 15 or so minutes to pump half a tank of gas. 2011 LT Tahoe 5.3. Whats the first thing that i need/should replace??

Thanks!

vent tube is plugged or the fill tube is kinked. mine doesnt take that long but i cant run the pump wide open.

Saturated charcoal canister from too much topping off the tank. Ask me how I know. I replaced the vent line and the canister and solved the problem. I blew out the line when the canister was off by blowing air into the fuel tank from the filler tube.
