Gas Tank swap? 1953 tank in a 1950 Pickup?

[ebruns1]

Hey Fellas,

My 1950 pickup truck project came with a crusty old tank that mounts behind the seat. I called the local radiator and tank repair place and they said it would run about $200 to boil out and clean up. A new tank is about $245 and mine is not a show truck. I don't like the idea of a tank inside the cab. Has anyone on here mounted the later model 1953 gas tank under the chassis in a 1948-1952 truck? Did the frame design change that radically where this would not be possible? I'd like to order a stock '53 tank and all the plumbing and cobble the mounting straps on my truck. I couldn't find any info in this forum on this idea, my apologies if it is here. Would someone please point me to the thread if this idea has already been explored? I've seen beer kegs, middle of the bed tanks but nothing on stock 1953-1957 tanks. If it fits I would be a happy camper! Thanks for any advice you can supply!
