So "still having problem" means you had the same problem you have now, correct? What parts did you replace and please tell me you used Genuine GM parts. "Most" of the evap system means what?

What the procedure for blowing out the lines?

I got 09 Yukon and it won't take gas. I disconnected the vent tube from the canister to troubleshoot for blocked can or solenoid stuck. It still won't take gas. Could be charcoal in the vent line to the tank? It doesn't looks like fun trying to disconnect from the tank to blow out. When I put gas in (even with the vent hose open to the atmosphere) the fill hose fills up and then I can hear it running down in the tank and sounds like the air is coming up the breather. I don't know what's going on. Did you get yours resolved?
