I have a new keg, new kegerator kit, with pass thru tap and an old corny keg too.
The MFL’s work like a charm on the old keg. On the new keg, I have to keep applying pressure to the co2 to get it into the keg and cant even get the tap line in properly.
I tend to break things, so I dont want to break things trying to force them on. But I am to the point where I am considering trying a tool (hammer) to knock it onto the post. Pushing as hard as I can with my hands isnt getting me anywhere.
I know co2 is getting in there (now that I am forcing the MFL down with my hand) and can see that with the release valve, but the line out even when I push on it like the co2 side I cant make it work.
