I RECENTLY PURCHASED A JBJ CO2 REGULATOR AND THE NEEDLE VALVE SUCKS!!! I CANT REGULATE THE CO2 AT ALL, ITS VER FRUSTRATING. IM WONDERING IF I CAN FIT A FABCO NEEDLE VLAVE INSTEAD, IS IT POSSIBLE?
Isn't the fabco an inline valve? Wheras the JBJ is attached directly to the solenoid.
If I'm right then you should be able to do it, fitting within the tubing. The issue would be getting the bubble counter attached after the valve, you may need an adaptor for that.
By the way, typing in full caps is generally regarded as shouting.
