My "F" is experiencing something I find odd (and a bit disturbing), Hoping to find an answer from my fellow 300 owners. I stopped at a gas station about 5 miles from home yesterday to purchase some gasoline. When I twisted the gas tank cap to remove it, there was enough pressure in the tank to almost blow the cap out of my hand. I put about 6 gallons of gasoline in, and drove home. When I got home I removed the cap again, and again there was already a significant amount of pressure in the tank. This has happened at least one other time this year, and a few times last year - but this doesn't occur every time I remove the cap immediately after driving (short or long distance). I could understand if there was a vacuum in the tank -- but not pressure! And after only 5 miles! Any ideas, anyone?
