That depends on what model year of Ford Explorer :
My ( 1995 ) Ford Explorer XLT holds ( 21 U.S. gallons )
2002 and newer ( 22.5 )
1991 to 1994 ( I believe that's 19.3 )
It holds 22.5 gallons of fuel.
The 2 door holds 17.5 gallons The 4 door holds 21.0 gallons
A 1996 Ford Explorer XLT has a ( 21 U.S. gallon ) fuel tank
( 16.8 gallons ) in the 2003 Ford Explorer Sport
It should be the same as my 1995 - 21 gallons (79.5 liters )
According to the 2013 Ford Explorer Owner Guide : ( 18.6 U.S. gallons )
( 21 ) U.S. gallons on the 2000 Ford Explorer four door
19.3 Gallons
22.5 gallons
18.6 gallons ( U.S. ) according to the 2012 Ford Explorer Owner Guide
I believe the 1992 Ford Explorer 4 door holds 19.3 U.S. gallons
The 2002 Ford Explorer ( 4 door ) holds 22.5 U.S. gallons
