re: GMC Yukon - Fuel Pump Shuts off Constantly While Filling Tank (SOLVED: update pg 2)

Can you give me more details about this process? I replaced the canister and cleared the purge line going to the engine along with replacing the canister and the solenoid canister as well. So my next move will be to disconnect the vent tube (gas tank to canister) and try filling up the tank. If the gas pump shuts off prematurely again then I know my vent on the gas tank is clogged and I’ll need to clear them out.

You said you did this without removing the tank and more detail would be helpful. I also don’t know what 400 lb mono is so excuse my ignorance.
