minor regulator

[dragonfly designs 56]

I havent used my minor in three some years. I hooked it up and nothing happens. are regulators fixable or do you have to buy a new one?
im so retarded. I am missing that key thing that goes in the middle of my regulator. can you tell its been five years, no wonder i have no pressure. I cant find the dam thing anywhere. Is this something you can buy?

What do you mean "nothing happens"? Did the regulator not register any pressure in the tank? In the hose? Did you try and change the pressure setting?

What brand of regulator do you have? The better quality regulators usually are repairable. Cheap ones usually are not.
