Agree with Birken, nice to see someone ask for assistance then use it, properly.
You are doing an awesome job there! Things with these systems get confusing. Ford also did some things different than the rest of the pack. If you are trying to combine the different set ups could be causing you issues.So, I have a little riddle. I think I know the answer but would like to hear what others have to say.
Prior to all of this I had noticed that one or more air leaks was draining both primary and secondary air tanks , generally overnight. After several extensive searches, the only leak that I could find was a small leak from the drain valve at the rear axle air tank. This tank is T’ed into the primary air system only. Why would this one leak drain both systems?View attachment 229428
