Dad,
Great write up
Whose mechanical FP gauge and isolator setup did you originally go with?
I have an autometer like that but the like from the isolator to the guage that contains the antifreeze is stainless braided line. I've never had a lick of trouble. It has remained within 1 lb compared to at the IP. The 1 pound variance is due to the thefact that the gauge is mounted a little higher than the isolator.
Before that I had an electric autometer setup that did not make it 7 miles after putting it in. Also at the time (few years ago) I believe autometer was not recommending their electric FP gauge/isolator setup for diesels. Vibration maybe?
Maybe they have got the issues remedied now. I have seen a few Autometer electric setups go belly up. But again, this was a while back.
Again, nice write up and enjoy staring at your new found info as you are going down the road.
