These senders have a 1/8” NPT fittings except for the SEN-03-3 which has 10mm. The engine and sender threads should
be cleaned before installation and no tape or sealant should be used on the threads. The threads are self-sealing. On
single terminal senders, if the sender is mounted away from the engine the sender case must be grounded. On dual
terminal senders either terminal is connected to the gauge GND and the remaining terminal is connected to SND.
Contact Dakota Digital if you need to special order a metric thread sender.
The sender must be Dakota Digital part SEN-03-1, 03-3, 03-5, 10-1, or 10-2 .
Sending units from other manufacturers
will cause incorrect readings. If a sender is not connected properly, the display will show “
”. If the SND terminal is
shorted to ground, the display will show “---”.
