I have an '88 F350 Crew Cab Dually. It is missing the rear tank. It calls for a 19 gallon tank. I found this http://broncograveyard.com/bronco/i-...s%20tanks&sy=8
.or this http://broncograveyard.com/bronco/i-...as%20tank&sy=8
I know the one it came with was flat enough that it did not hang far below the frame rails. The spare tire was mounted there. I figure I can put the spare in the bed as long as the tank fits between the frame rails.
Any opinions if this will work or not. I would like the extra capacity for towing. I only get about 8mpg and dont want to have to fill up more often than I have to.
