      I have a 2011 Suburban, It became difficult to put gas in it so after a little research I replaced the evap canister and blew out the line from the solenoid on the motor all the way back to the canister. it made no difference with the ability to fill the tank at other than super slow speed. A scan with testing abilities concluded that the solenoids are working. About 2 tablespoons of charcoal pellets had made it out of the old canister and into the vent line towards the engine. After clearing that it made no difference filling the tank. The suburban otherwise runs and drive normally. What would be the next step? Drop the tank and look for an obstruction in the tank vent?
