Its 11 00 in the morning here sunrise has well departed. :-)

    Thats a good quality sender, provided you make sure the casing is bonded electrically  its a simple two wire ohmic output.

    Is there not a part number on the casing or top ?

    You could try a safety ohmmeter across the leads and see what resistance there is. It might give you a clue.

    It is probably easier to check with it on the bench.

    I'm using a capacitive version, so no moving parts. 

    Connections and Fuel calibration should be in your install manual.
