Well Buc I spent the cold aspect morning looking at my old pressure tanks. I have three four gallon tanks. I think that is what you are referring to as junior tanks. I have two with plastic buttons and one with an aluminum button, all have the chain attached to them. My old memory banks told me somewhere amongst these tanks there are some without the chain. I found them, they were from the early 50’s. One came with my 14hp rude. The other came with my 51 25hp rude. The boys will correct me if I am wrong but the tank we now call the tall boy was first, probably around 49 or 50. Then they made a red six gallon shorter with a small decal on it. Does you tank have a place for the cotter pin to hold the chain for the cap? Those chains are kind of a pain if you are pouring gas out at the end of the season. It may have been swapped some time in the past.
No idea what is going on with the diaphragm.
