When cranking engine and with putting a vacuum pump on the fuel line at the carbs,I have air bubbles coming up from the pump inlet as viewed through the clear pump bowl. If I remove the gas cap while this is happening, I hear the leak inside the tank. And it is not holding a vacuum.
When I sealed the tank, there was no way to remove the fuel pickup from inside the tank, it is behind a baffle and I assume its welded/brazed/solderer to the tank outlet. All I could do is shove a pipe brush down the oulet to keep it clear. The pickup is not part of the sender like the later trucks.
From what I can figure out on the panels, the 1/2 ton tank is shorter and wider then the 1 ton tank since the 1 ton frame rails are closer together. Someone has put a 1/2 tank in my panel because it looks and measures identical to all the pictures of 1/2 ton tanks Ive seen, including the reproductions. And this 1/2 ton tank sits about 1" from my driveshaft, even through the tank is up against the frame.
