I just siphoned the fuel out of the F250, but I haven't removed the tank yet. Based on Mark's measurements for the 80, it's best to go with the S10 Blazer tank. I will double check after removing the F250 tank.

What year did you recommend the S10 blazer? I haven't taken the tank out of the F250 yet. Based on your information, the F250 is not the most suitable choice.
