Charcoal canister

[Noggles]

I just went through this last year with my 05 Tahoe and it was the vent lines like everyone else is saying. Gotta drop the tank and blow the lines out or replace them. I replaced mine and the charcoal canister and it fixed the issue.

My new Yukon is doing it as well when its cold outside so Im gonna need to do the job all over again.

When the fuel pump clicks OFF, your done. Don't try to force more fuel in.

You don't understand the problem. I'm having the same problem. Fuel guage shown almost empty and your trying to add fuel and the gas pump will shut off after just putting a small amount in the tank.
