it all depends on the cab/bed length. my reg cab long bed has dual 19 gallon tanks, the short bed has a 16g front tank and i believe a 19 gallon rear tank... ive squeezed 19.5 gallons in my front tank and 19 even in the rear, if you want more range, you can always swap in a bronco tank, 33 gallons. i plan on that after my engine and gear swap.
my chilton manual states:
front tank (SWB F150): 16.5 gal
front tank (LWB gas): 19.0 gal
front tank (LWB diesel): 20 to 22 gal (varies with model)
rear tank (exc. chassis cab and superduty): 18.2 gal
rear tank (chassis cab and superduty): 19 gal
