Is this sending unit compatible (ohms) with Faria Oil Pressure Gauge part # 12803?
The problem is this is a dual station so you will need to make sure that's what you need. You can use this with that gauge, but just know these specs: 240 ohms at 0 PSI, 103 ohms at 40 PSI, and 33.5 ohms at 80 PSI for a single station. Dual station senders have 1/2 the resistance value of single station senders. You can contact Sierra or Faria if you need some more technical advice.
