I need to know the gas tank size on my 1989 Mazda B2600i 4x4 Standard Cab, the title to the truck says its a b2600ishort... i reken the short means bed??? Any help on the size of the tank would be great... i ordered a 16 gallon today... hoping it was the correct one...

 

I was thinking my 92' short had a 13 in it, but now that I'm paying more attention to my gassing up. I getting as much as 15 in to what I thought was a 13. Either I'm getting ripped off or it's a 16.
