AC Question
Well since my previous thread was lost since I used a/c in the title I'm making another one.
I've found the leak which was so obvious I didn't need a UV leak detector but I used it anyways and checked the rest of the system. The leak was in the discharge line it was visually evident by the collection of oil on the line and upon using the UV pen the leak was revealed but where else between the rubber to metal hose union.
One question I have though is the discharge line has a cylindrical can connected to it what is this for and will the new hose include one?
Also I've located the orifice tube which I will be replacing along with the accumulator since the system will be open I see that there is one quick disconnect fitting on one end where the tube is I take that off then what?
Does the tube reside inside the pipe or is it part of the pipe and must be cut away and a new one must be spliced in?

Well I've ordered the parts and had the system evacuated after the repairs I intend to refill the system myself the label on the blower motor states that it is to be filled with 2.33 lbs of refrigerant since my system doesn't have auxillary A/C.
I also have a set of manifold gauges and the charts from the service manual to compare the pressures on the high and low side based on ambient temperature.
One thing that bothers me though is to my knowledge an A/C recovery system utilizes a vacuum pump to remove the refrigerant. Which leaves a residual vacuum in the system it is also safe to say that there is no oxygen in the system.
When I remove the hose oxygen will enter the system will this have any effect on the system or does the refrigerent simply displace it?

Also I need to replace the discharge line which connects the compressor to the condenser disconnecting it from the compressor side is no problem but what about the condensor side? The Ford service manual says to disconnect it at the quick disconnect.
There is no quick disconnect that I can see how is this hose connected to the condensor? It looks like the metal line just runs right into a machined port on the condensor with no visible way to remove it.

Once you've opened the system, you should put the vacuum to it again. The residual vacuum will pull the refrigerant into the system when you are ready to recharge.

Thanks for the vacuum tip.
Upon further condenser inspection I've noticed something.
I see two studs which are firmly affixed to nuts located under each hose. Will loosening these studs allow me to remove the hose?

Remember, there is a regular hose barb under the crimp. many times you can cut off the crimp collar, cut off an inch of hose and reattach for another 10 years. use refrigeration grade hose clamps.

Upon reading an A/C manual that "can" on the high side discharge line from the compressor is actually a muffler. Its purpose is to quiet the pumping noise from the compressor.
It also can't be flushed and since flushing the discharge line is necessary especially if you are recovering from the black death. You must remove it during the flushing process and either install a new one afterwards or braze on a solid length of pipe to eliminate it from the system. Since the author claims that they noticed no difference in system performance or noise with it gone.
