Rear of the jeep
The fuel tank is under the rear of the vehicle.
That Jeep had a 20 gallon tank
Either a 13 gallon or a 20 gallon tank.
I believe that the fuel tank in your jeep grand Cherokee is the same size of the fuel tank in my 2000 jeep Cherokee which would be 19.0 gallons
You have to drop your tank,it is inside the tank
Tank (US gallons) 20.00
