Yes Alvin, my panel is a half ton, it is virtually identical to yours, just one year newer. My tank is an original tank exactly like Alvin's photo. Billyray, you mention about not fastening it to the body, that is not even possible as it sits between the frame rails, quite far from any part of the body. The tank brackets fasten to the frame, through the floor and the rear bracket bolts to the frame rail with 3 bolts. My question really was with connecting the actual tank to the filler neck, using the rubber connecting hose that is exactly 3" long. The angles of the two filler necks don't line up very well. I also was wondering exactly how far the filler neck protrudes from the body.
