Kelley Monroe and I just installed a set of GPI bladder fuel tanks in my CJ. We are now at the fuel level calibration stage. My interpretation of the 'dialing in" instructions suggest that the pilot will only be able to tell how much fuel is in each tank(s) when their respective levels are below 63 litres...and that the gauge will not show or display the full 113 litre or 30 gallon available. How have the rest of you (~50 kits sold to date) addressed this problem? Send the fuel gauge out to be renumbered? Ignore the lack of real time fuel consumption data and stay cool until the needle starts to move off the "6"? Please give me some guidance.

The fuel level sending unit is a float type and senses the vertical position of the fuel surface. The fuel guage shows a maximum of 60 litres in the standard tank (probably because that is the maximum travel of the float arm in that particular sending unit) and with it installed in the larger tank it will also show 60 litres when the fuel surface is at the same height. The actual fuel quantity in the bladder will be something more than 60 litres. Whatever that number is it will represent the maximum guage reading for that particular system. It would be necessary to calibrate the system by adding fuel in 5 (or 10?) litre increments and noting the guage reading for each increment. With that information a calibration card could be produced showing the actual fuel quantity for each guage reading. That information could also be used to fabricate a new dial plate for the guage. In any case I doubt that the sending unit range is adequate to read the full fuel quantity. Walt PS: I note your spelling is in proper accordance with the King=99s English!!!!!!
