I am considering an under bed fuel tank for my 1950 restoration project. I have rebuild the 216. Runs like top top. But I am considering moving the fuel tank out of the cab. I am looking at the fuel tank from The Truck Shop in Orange CA. I can’t find any information on if the tank will just bolt in place. No modifications to the original chassis? I have looked for installation instructions but cannot find them on the internet. I am hoping it is just bolt in place. With this tank with the standard fuel pump? And information is appreciated. Thank you.

I put a brothers tank in my 58. Drill holes and bolt up. The mechanical fuel pump works fine at that distance. I had trouble with a "hinge" type sending unit. Inner walls of tank were too close. 15 feet of braided fuel line was enough. I had to remove the spare tire rack.

Thank you for the input. I will check out the Brothers tank. I like the idea of a SS tank. I was set on the Truck Shop tank because it also comes with all the supplies required. Also, thank for the great picture. That really helps.

Will an original 47.2/48 under the bed tank fit? Did the 49 frame change from the 48? What about fitting a 48 tank forward of the rear axle on a 54 3100? I have been thinking about moving the gas tank in my 54 3100 out of the cab. I just recently added an underbed spare tire carrier so I would have to put the tank in front of the rear axle where they were located in 47/48.

The early-style 47-48 frame-mount tank should fit your 54, but you'll have to relocate your filler neck and fill the hole in the side of your cab.
I've always assumed that the 47-54 Panel/Suburban side-mount gas tank is the same as the original 47-48 pickup tank. I see them available in reproduction.
Where does the filler neck come out on a 47-48 pickup?

Thanks Tim! It appears to come out the side of the bed below the floor. I need to replace my in cab tank and have been considering the 47-48 tank option.

If installing a 47 fuel tank in a 49-53 truck you will need to replace one or two cross sills. The original 47 sill was notched to allow the tank to tuck up closer to the wood floor. Either notch your existing sill to accommodate the tank or use a repro or original cross sill for that application. Installing in a 54-55 will be a problem because the wood floor is about 2" lower and will cause the tank to hang well below the frame.
Do you know how the straps are mounted to the truck. Borrowed the illustration from LMC Truck.
