FUEL SETUP
The control box can read seven common fuel level sender resistance values. If your
sender is not shown in the table below, the system can be programmed to read a custom sender.
The table below shows the seven pre-programmed senders and their respective empty and full
resistance values.

You will need to have the sender out of the tank, or begin with the tank empty and
add fuel during the custom fuel sender setup.
*** The factory default custom curve is 110 empty and 5 ohms full
***You must select “

”, release SW1.
The message display will show “

resistance the control box is seeing from the fuel sensor. You should be able to move
the float up and down at this point and see the resistance values follow the curve of
your sensor.
