The 1939-47 Dodge tank is shorter than the 1948-53 Dodge Truck tanks. Also, the neck is at a slightly different angle.
The newer trucks used a tank that was 3.5 inches longer than the 39-47 Tanks, Therefore, it requires a bracket at the end of the tank, to the rear, to be constructed to support that end of the shorter tank. A similar bracket was used in the 39-47 Dodge trucks, that had a longer wheelbase than the 116 of the half ton trucks. Example is the 120" and 133" trucks. To use the shorter tank in the B Series trucks.
It requires a triangle shaped bracket, one side bolted to the frame side (two bolts) and the bottom of frame (one bolt), and the bottom of the triangle would be bolted to the holes in the flange of the gas tank. As for the front end, the bolt holes on the tank flange line up perfectly with the cross member mounting holes, just the same as the 39-47 trucks, and the angled filler neck lines up with the hole in cab floor. However, it is a slightly different angle and some simple modifications must be made.
The hole in floor should be enlarged about 1 inch on left side to allow connection to filler tube. That tube is longer and has a crook in it that should be removed. (inlet on side of cab is lower on the body) So, simply cutting off the bottom 5 inches of the steel filler neck and using a longer rubber hose connection will allow good fit.Use about 10 of hose instead of the 5 inches. Tank fits well on the top, and on both sides there is clearance, basically the same as the 39-47 Dodge trucks.
