I've done this and found that somewhere in the tubing to bulkhead to rigid tube transition there is an air leak. Dosing line is always getting air bubbles in it. Only work around for now is to put the dosing tube directly in the container. Any ideas to fix it? I've already done the obvious, clean cut on all tubing, removed burrs, no debris, etc.

I saved the jugs from my AquaForest 3pt and I have my MTC dual chamber air powered Prodoser that I’m going to retrofit. 0616429C-8558-4970-91DD-3BAA905939CC.jpeg
Been wanting to use it for about 10-15 years I don’t have a doser yet. Looking into that next year. Have to figure out what’s good.

Is that tube the 1/4" tube that fit into 1/4 air line? I got some from LFS, but they don't seem to fit. I have to put a part of air tubes on it, then put it in for it to stay.
Typically airline is too soft and pliable to work with push connect fittings and create a seal. The tubing in this video is the same 1/4" tubing we use for RODI units. :)

I've had the same experiences before, but I've been able to resolve them from disconnecting and reconnecting the lines. If you're using the polyethylene 1/4" tubing for the dosing lines, it shouldn't have a problem sealing. You could also try replacing the bulkhead with new one to see if that particular bulkhead is the issue. :)
