On the 1984 Jaguar XJ6, the fuel pumps are located in the fuel tank and under the car near the rear axle. The in-tank pump is responsible for drawing fuel from the tank, while the external pump helps maintain pressure in the fuel delivery system. Accessing the in-tank pump typically requires removing the rear seat and accessing the tank from above. The external pump can be accessed from underneath the vehicle.
