My tank has been leaking or over a decade when topped off. I think that it is leaking from the plastic nut or the that part of tank that holds the fuel pump in place. if I trickle in the gas the filler hose never over fills and the fuel just drips from the bottom. I am not able to drop the tank with out breaking bolts (too much rust). I am not able to find an affordable 19 gallon tank anywhere. I would like to keep the parts prices below $250. Do you have any recommendations?
