The NOS tank may be for a one ton Panel/Suburban/Canopy Express. There were no 3/4 ton 1947/55 Panels/Suburban/Canopy Expresses built. Only 1/2 ton and 1 ton units.
For some reason that longer tank filler neck looks to be wrong for the panel. It should have the same curve as the one Alvin has. This may have been for a 1 1/2 ton or larger grain truck that had the saddle tank on the outside. I have seen all three tanks, but did not take pictures of the difference. The 1954/55 tank may be slightly different and the sending unit is definitely different. The pickup tube is with the sending unit on the 1954/55 Panel/Suburban/Canopy Express. The 1947/49 pick up trucks gas tanks were also mounted underneath the bed, they had a slightly different filler neck and tank dimensions.

HIS ALBUM ON THE GAS TANK AND STRAPS OLD LINK ON THE SAME SUBJECT ANOTHER LINK ON GAS TANKS Tim can chime in too! I think he confirmed the gas tanks to be 16 gallons for the 1/2 ton and 18 gallons for the 1 ton. He also says the 1947/48 pickup tank is a 17.5 gallon tank and is different than the 1947/55 Panels/Suburban/Canopy Expresses
