What tank does my truck have? It's a single tank in front of rear wheels and runs along drivers side.
Wait till its almost or just below empty and when you fill it up, you will have your answer. Then take that information (total gallons) with year, make (F-250) and model (Super Duty, XLT, 4WD, wheelbase length) to your local Ford dealer to get a part number if that is what you need.
38 gallons....may be in a couple of receptacles~
