C, have you pulled that screw to see what's in there, here's a tip, if you have access to an MDS remote needle, they are excellent and can withstand the pressure of a Cline regulator setup. The Cline setup puts a serious bulge in those stiff walled Sullivan tanks.Here is one pictured on a Fitzpatrick .61.
