No difference in tanks between 1/2 ton, 3/4 ton, and 1 ton. Almost all 2 ton to 3 ton, during the time period, have the same size tank, GM standard issue 19 gallon, with two gallons sloshing out.
Really big trucks, big engine, often diesel, frequently will have side frame saddle tanks, I think in the 30 gallon to 50 gallon range. Never had the pleasure of working on one of those.
Standard pickup, for this time period we are discussing, behind the seat 19 gallon. For panel trucks, 19 gallon between frame members. My 1948 GMC 3 ton has the standard issue behind the seat 19 gallon tank, same common GM tank, including sending unit. GMC, Chevy, no difference; production line tank.
Payload does not make a difference in fuel tanks until you get up into the really big trucks. This is beyond stove bolt and big bolt, this is gigantic bolt.
Anyone know if GM offered optional larger fuel tanks? Highly unlikely a tank smaller than 19 gallons was offered during the time period.
