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 is not connected properly, the display will show "EEE". If the SND terminal is shorted to ground, the display
will show "---".
Connect to a main ground location.
Connect to fused switched 12 VDC power. (An accessory terminal will work for this.)
