I have had my Lemo 2 for about a month now and really like it. I drive for work and the top fill makes it very convenient for me when it's busy and I don't have the time to pull over. Lately I have been having a hard time opening and closing the fill port door. It use to work easily but now I need to use pliers. When disassembled it works easier, but once together, almost impossible. Anyone have this issue or any suggestions? Mahalo
