2000 Grand Caravan with 133K miles. About a week ago I noticed a faint fuel smell back by the gas cap. Friday the Check Engine Light came on and the code was P0455 (Evap Leak - Large). I replaced the cap with the dealer part. Pulled the negative cable on the battery to reset codes. Hoping that's the end of it.
Thinking that it might be more than the cap I jacked up the driver side rear, removed the tire and plastic skirt to reveal the Fuel Tank Filler Neck. Very rusty but I didn't notice any cracks. If the P0455 comes back and if I wanted to replace that entire filler neck assembly, I have a question. The neck has a small metal tube that connects to a plastic hose. I can't figure out how to disconnect this. Do I squeeze the plastic connector, turn it or pull it?
Here is s close up of the connector I can't figure out:
Here is a picture of my entire filler neck assmbly:
