One of my Marks(97) cranks over but won't turn on. Engine light came on which the scan tool revealed, U1201 - SCP(J1850) Missing or Invalid Data for Air Conditioning Clutch.

Looking up code U1201 & J1850 led to this helpful post about the A/C Clutch, I wasn't aware low refrigerant could prevent the engine from firing up.
No Cooling Fan or A/C Clutch

I took a look and noticed a leak where the Compressor to Condenser Discharge lines connect, this explains the A/C compressor recently cycling On/Off. Further inspection resulted in a grey(or light brown) ring that I assume should be somewhere within the spring lock clip assembly.

The workshop manual doesn't mention anything about this ring, but looking at this listing for a similar Discharge assembly leads me to think the ring belongs within the discharge tube.

What would the likely fix be: Replacing the Condensor Discharge line assembly or simply reinstalling the ring and replacing the o-ring seals?
