Identify all the parts in your fuel system, and the engine size. is your's
2 wheel drive with one tank at the rear, then is there just one electric
pump? or is there a lift pump in the tank that supplies a "rail pump?.
You say you have a carburetor, but do you actually have CFI ? you
see so many parts were for different systems, then valves or
selectors, cannister type filter back by the tank, etc. you must do
some identification of what was in use, get Ford parts to help you
determine what parts are in use on yours and supplying what delivery
system. See what questions they have, and ways they may tell you to
identify. Some fuel parts had to be matched up. it always helps to
have the month and year, VIN, gvw, engine size and delivery system
type or calibration code.
See what they ask and go step by step.
