i want to replace my Sunpro 2" white faced voltmeter with an Equus 2" black faced voltmeter. Both meters have the same sweep and same temperature range. My question is: Can I use the sending unit of the Sunpro voltmeter with the Equus voltmeter? This will save me the trouble of removing the Sunpro sender and installing the Equus sender.

I'll answer my question. The ohmic values of both sensors are the same at any given temperature range. The sweep is the same and the markers are the same so the sensors are interchangable.
