01 GC A/C reading high pressure

Hello. Replaced the condenser coil, pulled a vacuum and filled the system. Reading high pressure @ the fill port. Need to replace the ex. valves? How to test if I need one or both? Thanks

Welcome to DF
There two ports,one for discharge and the other is suction. Which one are you getting the high pressure reading?

Thanks for the fast response. readings taken @ the low pressure line (large tube) leading to the compressor. reading now 65 psi. cycles down to 10 when compressor starts.

65 normal for static pressure, 10 a bit low when compressor is engaged.
