For a 1991 Ford Taurus :
According to my Chilton's Auto Repair Manual :
( 16.0 U.S. gallons or the optional extended range tank which is 18.6 )
According to the 2002 Ford Taurus Owner Guide : ( 68.1 litres / 18.0 U.S. gallons )
I believe that is ( 19.3 U.S. gallons ) in a 1991 Ford Explorer 4 door
No they are the same size. They are both 16 gallon tanks. I hope this helps you.
