I got a true brand cooler. I put a new cap tube and filter drier. It's seems to be running ok but the low side seems to low.

The cooler holds a 10 oz charge r134a
I'm getting about 28 psi resting

When running the low side is 13 psi or 11 degrees F
High side 130 psi or about 100 degrees F
The evaporator was 20 degrees F

Cooler is holding good at 40 degrees F.

Cap tube is 12 ft of .064 in

Is the system still restricted? Is it ok to run it?
