Ok folks, an update on the digital temp probe on the injector line. I put a battery in it today for my drive to Toronto. It was about -10C when I left, once the truck was up to temp and I was running down the highway (100km/hr) the temp on the rear injector (still running diesel!) got up to about 15C. Continual running (I drove about 150km) got me up eventually to about 20 to 25C. At this point I stopped to get a bite to eat, shut the truck off and went inside... When I came back out the temperature had gone up to 45C - Quite a jump! That tells me that there is a LOT of heat loss due to airflow, both over the engine and over the injector lines. My goal here is to insulate the injector lines to protect against this heat loss... Within about a minute of re-entering the highway, the injector temp had dropped back down to 25C....
