Mounting: 

The gauge requires a round hole 2-

1/16“ in diameter.  It should be inserted into the opening from the front 

and the U-clamp will be installed from the back.  Tighten the two nuts on the U-clamp so that the gauge is secure.  
Gauge depth to the back of the case is 1”.  Gauge depth including the mounting studs is 1-7/8”.

These senders have a tapered self-sealing thread.  The engine and sender threads should be cleaned before 
installation and no tape or sealant should be used on the threads.  The sender is typically mounted in the oil tank or 
it can replace the drain plug on some models.  Make sure that the sender tip can get into the oil flow.  

The sender 

must be a Dakota Digital temp unit.

  Sending units from other manufacturers will cause incorrect readings.  If a 

sender i

s not connected properly, the display will show “EEE”.  If the SND terminal is shorted to ground, the display 

will show “---”.
