Hi jimbo I hope I can help you herethe thing that really makes me think here you say you feel dampness on the upper part of the tank so this does lead me to think that lee fuel leak is up top of the tank so no matter what it sounds like i would be droping the fuel tank you may have rubbed a small hole in top of tank you may have the fuel pump o ring leaking it could be a hose but you are gonna have to drop tank to see i would also check my fuel canester hope this helps thanks al
