Jaguar XJ6 Problem Report
Jaguar XJ6 Water May Accumulate in the Fuel Filler Neck Cavity Due to a Blocked Drain
After the car has been washed or in the rain, the cavity around the fuel filler neck may be filled with water due to a blocked drain. The water and debris can then enter the gas tank when the gas cap is removed for refueling. It is recommended to clear the cavity of any water or debris before removing the fuel cap.
