I want to know where to get these two items if possible?

I usally wait a long time before switching over but want to shorten that time besides there also needs to be a way to monitor the vacume of the oil in the line. I was thinking of autometer or otther gage/sender. PS if thay are mechanical all the better.

Hi Joe. Try to 411 John Sherman Agency in Vancouver. That's where I bought my RTD probe.

Just google it there are several places online that sell these type of gauges.
