Thanks for taking the time to respond :). Did you put ports in your hoses? Thought I would put a port to measure the high side pressure in the hose where it runs behind the grill, easy enough to take out. Or I guess I could get a fitting that has one in it, and put it just before it attaches to the top conderser inlet. Thought about putting, the low pressure port/ fill on the hose from the evaporator maybe just after the bracket on the cam cover before it goes to the compressor. My compressor has no fill ports behind an R134. Unit.
