I fixed the fresh tank support today. The tank is of course held up by two rails that go from one side of the frame to the other. The back rail was welded on the frame and looked good. The front rail was held up on one side by three self tapping screws and believe it or not on the other side by only two self tapping screws.
I drilled out all the screws and replaced them with 4 through bolts on each side. The rails were sturdy and the tank was held in well when the rail was fastened properly. I did add a couple of strips of nylon webbing from rail to rail just for added support.
