A/C System Pressure
Last week while out in my 95 i turned A/C on and seemed to be lower output then last year. Got some 134A today and went to fill it. Showed only 25 pounds on gauge before addition and would not go any higher then 35. The temps at the interior ducts were much better with charge, but wondering if 35 pounds is normal in the C4 since the gauge on the 134A tank showed it to be only half way in the green range? Hoping that any leak in system will be resolved by the sealant included in the 134A.

I do understand that the gauges the on the DYI tanks may not be 100% accurate but I'm guessing they aren't widely off the mark. Was just looking to see what others have found their system pressure to be at when full.
