Hello, I am having trouble with trying to put fuel in my tank. Nozzle keeps shutting off . The vehicle is a 2005 class c motorhome on chev express chassis, 6 litre engine. We are travelling and this just started with the last two fill ups. Maybe a evap vent problem? Any suggestions are appreciated, thanks in advance.

 

On my 07 Tahoe the charcoal canister membranes failed and allowed the charcoal pellets to clog up the vent line, causing the problem you have.
