I have a 1994 XLT xtended cab...with two tanks, each can hold 16gals.
On the 1987 Ford F150 with dual tanks the fuel filter mounted on the inside of the frame under the cab on the driver's side. Be sure you have the right tools to change the filter, and absolutely use eye protection. There will be fuel leakage, you do not want it in your eye.
