I have checked the lines from the compressor (sanden 508) and dryer with no luck. the compressor line goes into the cab behind the dash and connects into another cooling fin setup? the other just goes to the dryer and condenser. Where are the hi low ports on this thing? I know not a needed function but I like everything to work.
check the back of the compressor also check the low side line,large diameter,under the hood just above the top of engine also look on right side of engine ,pass side,down by the radiator.hope this helps.
