Holy crap! This totally makes sense now with what I have experienced. Don't understand why, but just saying...bought truck, drove 1800 miles home no coolant leak, do full service and top everything off including coolant in degas to cold fill line, now it pukes a little out about every other time I drive it. The level it was at when I bought it was about 1.5" below cold line on bottle. Guess I should remove some again and keep an eye on it?

OK, if you are following this, here's where I am so far. Picked up my new degas tank and began installation. Every thing was going great untill I broke off the pit **** (cheap plastic). Can't get one untill tomorrow. Here are some pics. The tanks look much the same to me except for where the cold fill lines are. The inlet is in the same place on the new as on the old. Upper inlet on the old was blocked off. I think I could have drawn a couple lines with a felt tip and had the same out come. I wish I had taken a picture of where my coolant level was yesterday. I would say it was right about the center of the cold fill lines on the new tank. I remain puzzeled about why but that's where it was and where it worked. I do note that the new tank says do not over fill. I bet if you do the truck will puke on hard pulls.
I also recall that when I first moved over here from the 7.3 forum letting the coolant get below the inlet was a big no no because air would get in and cause cavitation. I guess that wasn't really true.

it would be interesting after you have some proven miles and pulls on it with the coolant in the proper fill range and no puking to "overfill " it to roughly the old full range to see if it would puke like it has to eliminate the possibility of the new tank just sealing better than the old one.

I'll have to take a better picture, to my eye the top of the inlet pipe was 2 inches on both tanks. There may be some difference on the bottom as I did not compare them as closely as I did the tanks.

I am thinking the new tank and the new fill line will stop the puking. I know it did with ours. The only thing they didn't check were the Tstats that I had already mentioned and that's when we had the front cover failure caused by the cavitation. That truck was in no way ran nearly as hard as yours. It idled a lot. After the tankand updated cap, we never had another puking issue. Maybe you are on the downhill side of this problem!

New tank is in and coolant up to proper cold fill line. There may be some air still but I let it idle hot with heater working so maybe I got the air out.
Took it out on I 85 and horsed it around as much as I could in rush hour traffic. Got over 30 PSI of boost several times. It did not puke. So maybe this is over. I won't know for sure until I tow down to Florida at the end of the month but I have a good feeling right now.
I want to thank y'all for hanging with me and helping me work through it. it's nice to have a sounding board to help in the decision making. A special thanks to senix who seems to always be right on the issues. Now if he would just tell us what changed. The truck just started puking on hard pulls after 65,000 miles.
I did notice the coolant container has changed and the name is now MC Gold Concentrate. I wonder if the contents changed, it looks less gold than it used to. Couldn't have caused my pukes though as all I put in before today was the Gold in the white jugs.
OK, I'm outta here for now. If anything goes south on me I'll probably start a new thread. Thanks again y'all.

We leave for Fort myers later this month. Can't find much of a hill between here and there but I can set up some zero to whatever runs on the way down. That should let me know one way or the other. I'll send a report either way.

just looking at the two tanks, if using the old tank would moving your small return hose to the top and block the lower port on the tank give the same results as a the new updated tank? or do you think you need the head space of having less coolant in the tank?
