Depends how much fuel you put in it
3000 gallons of Jet fuel
Internally, an F-18 jet can hold 14,400lbs of fuel.
the ammount of fuel a fighter jet uses depends on they type of aircraft EG. how many engines, how big they are ect. for example the SR-71A blackbird uses around 3.6 kilalitres of fuel an hour
An F-16 fighter jet typically has a fuel capacity of around 7,000 pounds (approximately 3,175 kilograms) when using its internal fuel tanks. This can be increased with external fuel tanks, which can add an additional 1,000 to 2,000 pounds of fuel, depending on the configuration. The total fuel capacity allows for a combat radius of around 300 miles (480 kilometers) without refueling, depending on the mission profile.
Most modern fighters carry 1,500 -2,000 gallons of fuel.
The fuel capacity of a fighter jet varies widely depending on the model. For example, the F-16 Fighting Falcon can carry around 7,000 pounds (about 3,175 kg) of fuel, while the F/A-18 Hornet can hold approximately 14,500 pounds (about 6,577 kg). Larger jets like the F-15 Eagle can carry around 13,000 pounds (about 5,897 kg) of internal fuel, with additional capacity when using external tanks. Overall, fuel capacity is designed to support the jet's range and mission profile.
NATO countries use JP-8, which is a kerosene-based fuel.
Freighter or fighter jet or fuel truck
The F-22 Raptor can hold about 3,050 gallons or 20,333 pounds of JP-8 jet fuel internally.
Every fighter jet is different. For the F22 Raptor most of the fuel is used doing high speed maneuvers and flying at supersonic speeds. While on a carrier, the F-22 uses very little fuel due to catapult and flying into the wind to help elevate the fighter jet.
