Ok. I discovered something interesting about this fuel leak. The problem has been trying to duplicate it. It's so infrequent its almost impossible. I sometimes camp in my van, and on my last trip i heard what I thought was a small animal under my van...it made strange sound...almost like something at cycled or a solenoid activating. 15 seconds i smell gas. It was middle of the night van had not ran for over 10 hours. I don't know what to think of it. It seems no one has seen a leak, only vapor.
