Clean, very useable tank. One of the mounting holes in the rear has the 10mm mounting bolt stuck in it, the nut on the inside of the tank is spinning. I used a pair of wire snips to make a single cut in my plastics so they would slide on, but still hold and never had a problem that way. Maybe someone can fix it, or do the same thing i did. Just pay shipping, i just want it out of my garage.
