I removed my under bed fuel tank from my 47-48 3/4 ton. It is not like what is pictured available in the after market parts suppliers. It measures 7 1/4" deep x 12" wide and 41" long. It is supported from two brackets that are riveted to the frame and straps that go under it from the frame to the end of the bracket by the drive shaft side. The fill spout is located on the top near the rear and the gauge sending unit is also on the top just in front of the fill spout. The cross sills are way above and do not come anywhere close enough to the tank for any interference. Is there anyone that reproduces the proper tank for the 47-48 under bed tanks? I can repair my tank (dents) but I would consider a new one if it was available.
