In cab gas tank problems...
Hey guys and gals,
I have a 76 F250 with an in cab tank. I ran out of gas the other day when my gauge still said I had an 1/8 of a tank left. I figured I might as well check it out since I'm smelling gas after I fill up with more than 7 gallons. So, after draining the tank while it was in the truck I remove it to find that I still have 2 or so gallons still in it. The pick up tube looks like it is sitting on the bottom of the tank or maybe a 1/16 inch off the bottom. Anyone have any ideas why I'm not getting the last 2 gallons? Is this normal? Anyone else have a gauge that reads not empty at empty? The gas smell was a bad gasket on the sending unit.

How does the siphon tube come out? The fitting looks like it is brazed onto the tank. I was thinking the same thing but the inside of the tank looks very clean. I figured if the inside was even a little rusty then the tube could possibly have corroded, too. But then again, what else could it be if not a pin hole in the siphon tube. Is there a way to adjust the gauge like Bama suggested?

You can gently bend the float arm to adjust it.

I'll try tweaking the float arm a bit. And thanks in advance, Dr_Gonzo, for checking your siphon tube.
