ok, i looked at the web site, according to the instructions it is a mechanical unit. what you can do it locate your temperature sending unit, i can locate it on the parts computer tomm. and repost or someone els out there can post it before that, anyway. remove the sensor, take that sensor and your new sensor down to a hardware store and try to locate a brass t. once you describe what you are after they should be able to help just fine. then you can install both sensors in one port and keep both gauges. :laugh: p.s. since you will be taking things apart and you want them to seal up good afterwards, while at the hardware store purchase some of the liquid teflon tape (in a tube) that stuff rocks and works 100 times better than regualr teflon tape. it will never leak. plus you will use it around the house for the next 20 years.
