I'm running a 13.2 gal gas tank from a 83-85 blazer. It's only 8 7/8 tall so it won't hang below the bed and it fits betreen the rails really nice. I got mine form a buddy at oriley auto parts for about 200 with the sending unit. The part munber for the tank is gm19a and I forgot what the sending unit was.
