Thanks to the post from Chris I was able to do this. Truly hope it works.
The doser plastic connectors were clogged besides tubing. I replaced tubing and used a pin to clear the connectors.
My 2st T was to small because ATO has a larger tube.
Found these grey ones and again to small but disabled valve and it fit the ATO perfectly.
Heated hot water to soak the airline tubing and slid on to connectors easily. Pics below.
