On a 36 Ford original King Seely gas gauge and sending unit does the float sit above or below the wire hoop? I have the float below the hoop and I read over full. I bent the arm but now I seem to be not reading empty correctly. Thanks. Any information appreciated. Goldfinch28

I think 1936 is the same, but 1936 owners can tell you for sure.
Read Post #6 in thread belkow:

You have to have the patience of a toothache once you pry off the top of the sending unit and start adjusting the star wheel. Be very gentle. IT'S ONLY FOR "FINE TUNING ADJUSTMENT OF YOU GAUGE NEEDLE." MAJOR ADJUSTMENT IS DETERMINED BY LENGTH AND BEND IN THE FLOAT ARM.

Plus, make sure your float has no hairline cracks as sometimes happens.

The location of your float (as described in your post) in an OEM King-Seeley thermal fuel sending unit is not what determines the empty/full readings at the dash gauge (there are calibrations made inside the fuel sending unit and at the gauge to pair/calibrate the two). The float position at full and empty is important relative to the travel towards the top and bottom of your fuel tank...if the float contacts the top or the bottom of the fuel tank when installed then the sending unit will not be reaching its maximum sweep (as determined by the sending unit stops) and thus your gauge is guaranteed not to reach its respective Full or Empty.
