We have way different coaches and years... but on our coach the blue-capped AC port is about one foot, maybe 15", above the front of the generator and behind the coach's front cap.  Our generator slides out the front... don't know about yours.  I push the generator out about a foot... just so I can get my left arm in there with my hand straight up and my elbow just about resting on the top of the generator.  I have read here on the Forum that some coaches have AC ports back near the AC pump on the engine.

I located the low pressure port in the rear. Started to recharge system and high pressure line near schrader valve is leaking and line will need replacing. Is the line a shelf item or does it require a custom item. I attached a photo

for future reference. Thanks as always.

Gary,
Just so you know, there is no photo attachment, at least not for me.

Gary,
The high side line (hose) is not a stock, off shelf item. They were made-up at the assembly plant as needed. But any large automotive A/C shop can fabricate a new line to match the old one. However, if the line is a long run, it would be better to just splice a section to the end to replace the defective area if you have or can get a crimping tool.

Gary
        I just wanted to pass on to you some information regarding your A/C, seeings we have the same year and model of coach.
 Keep an eye on your compressor for any leakage of lubricant or any other symptom that may warrant replacement. If such an event were to come about, make sure the replacement compressor is a "Sanden made in USA" and not a Chinese knockoff. Myself and one other Beaver Marquis owner went through this at the same time and same location. The Chinese knockoffs will be advertised as "Sanden Like" or "Sanden Type" which are inferior to the Sanden's made in the USA. This information was obtained from Sanden and also a Distributor of Sanden compressors.
