Air Gauge Sending Unit

[eng309]

Own a 2006 Newmar Kountry Star DP Spartan Mountain Master Chassis. I need a new air gauge sending unit. I've called Spartan several times, left messages, emailed, sent smoke signals etc. trying to find out exactly what sending unit I need. I believe it is a Stewart Warner M 412-M but not 100% sure. Also Stewart Warner makes a p/n 82894 which looks very similar. Hence my confusion. Either way I know they are on back order from Summit Racing and everywhere else. Would appreciate if anyone knows the correct model number of the unit I need.

Thanks!!
