The Stovebolt Site Forums The Shop Area Making a Stovebolt Bed 1947-53 bed with extra hole ?

I traded for a few truck beds today and one has an extra hole I haven't seen before. 47- 53 style bed with a hole on passenger side behind stake pocket that looks like a gas fill hole, factory punched hole that still has what looks like Forester green paint.
What bed do I have?

1947 and 1948 trucks had the fuel tank under the bed, and the filler thru the passenger side of the bed. Fuel tank moved into the cab in 1949.

Thanks I didn't know they put them in the bed, my 47 one ton is between the bed and cab

Not in the bed, attached to the frame under the bed.
