The Jaguar XJ6 that has dual tanks holds 10 gallons in each tank. There is a tank change solenoid right below the power radio antenna in the trunk. The solenoid may be replaced with a similar solenoid or the solenoid can be replaced with a tee. This will allow the gas to equalize in both tanks. The down side of the tee is that you must still fill both tanks as the gas cannot equalize as fast as one tank is filled. You must also remember that the gas gauge is indicating the gas level of both tanks. Older tanks may have a lot of rust in them. Rock Valley Auto had replacement tanks at a reasonable cost compared to cleaning the old tanks. Mel
The solenoid is located on the driver's side of the truck just behind the EGR valve. It is held in place by two 8MM screws. There are two small rubber hoses on the bottom that must be removed and there is an electrical connection that must be unplugged. Screw in the two screws to mount the new one, replug in the electrical connection and reinstall the two rubber hoses near the bottom. I replaced mine this morning in about 10 minutes. You can purchase a new solenoid at NAPA for about $31. Good luck.
