Re: quick ??? on gas tank?
Sounds like the float is out of adjustment. As to only being able to use one tank, that sounds like a wiring or switching valve problem. Could also be the switch in the dash, but my guess is the valve under the truck. Have a friend sit in the truck and flip the switch while you listen to the valve under the truck. If you can't hear anything, replace it. I got mine at NAPA, granted our valves are a little different since mine is a 1989 R3500. Same principle though. Good luck with it.

Re: quick ??? on gas tank?
Yes - it's a 16 gallon tank, but keep in mind not all of that is "usable".
So, depending on how much is laying in the bottom, and how low you run it down 10 to 12 gallons on a "fill up" could be reasonable. K
