I have a 45 gallon aux. tank and solenoid valve on mine and flip the switch inside when I need it and turn it off when I'm full. On my 2003 I just had a manual valve and left it open all the time and after driving ~150 miles my fuel gauge would show empty but once the aux. tank ran empty and my main tank level started dropping the fuel gauge would start showing a level again.
