One of the steel tubes is 1/4OD - 5/32 ID, the other tube is 5/16 OD -1/4 ID .
The plastic tube coming out of the top of the automatic filling unit is 5/16 OD - 3/16 ID, a 26” section came with the unit, I could not find any of this in my town so I found an adapter that would allow me to add another 20” of the 3/8OD tube. When I first hooked up the unit I only used the 26” section and it worked fine. I wanted to make it longer so I added 40” of tube and it would not work. I cut it in half and all was well.
I used 10 foot section of 3/8 OD plastic tubing from the jug to the pump. No reason why 10 foot but when I bought it at the hardware store that sounded like a good number. When I got home I wanted to start with a long section. You know it is easier to cut it, than add it back later.
I just made do with what I could find at my locate Ace Hardware. They sell severial sizes of plastic 90 degree tube connectors. I bet you could use this in a bung instead of Stainless Steel tubing.
