It can be moved anywhere in that line, but in the same place between the components.
You don't HAVE to have a high side fittings.

In an email or something?
Really? you don't need a service port on the high pressure side? What is it for?
I feel pretty ignorant on AC systems.
My only real experience with AC systems up to this point has for the most part been removing them. Getting older and gotten spoiled with a few vehicles that have AC and think I need it now.
I don't know how many trucks I have had where the existing AC system was already hacked up and mostly removed. Tried to get one going on my Crew cab. Never worked very long.
Hopefully I can make this one work.

It is only there to monitor pressure really. It is kind of hack, but you don't have to have that service port. I would still put one in though.

Yes....if/when I hear something I'll post it in this thread K?
On every system I have worked on, the orifice tube or expansion valve has been outside the evaporator enclosure. All of the Chevy trucks I have done were orifice tubes and all of the tractors and semis have had expansion valves. I personally like the stupid simplicity of orifice tube systems. The service ports on my 01 burb are right next to the orifice tube, hi side immideately before and low side immedeately after. It's the way they should ALL be set up IMO.

I'm another big advocate for the orifice tube, I work on AG equipment daily and all the newer system are orifice tubes.
I found a few things out today.
Expansion valve is outside the evaporator enclosure but it is behind the firewall so that is why I wasn't seeing that. Put the box under the dash in a while ago and don't remember exactly what it looks like.
The service ports... Vintage air recommends they be in the hoses that go to the compressor. They do not necessarily need to be directly on the back of the compressor which makes all the difference for this install.
The Cummins compressor works perfectly with the Vintage air parts however for me, I had to order a couple different fittings to make the hoses go where I wanted them to. The service ports they send you in the universal hose kit are a 135 degree fitting. Presumably to bring the hoses forward out of the compressor. I need mine to go back a little bit and loop around.
Soon as my crimper shows up, i'll make up the AC lines and put it together.

Let us know how the crimper works. Been looking at one of those to redo my vintage cars ac units. Change them all over to barrier hoses.
From Vintage Air:
We prefer the High side service port to be in the High side gas line from the compressor to the condenser and it can be anywhere in that line. If you have to put the port in the -6 line, it needs to between the condenser and drier.

Pretty much what they had said to me. To have it in the line that is directly attached to the compressor. Both high and low pressure service ports.
Will do. Waiting on a few fittings from vintage air now. When those arrive, i'll make up some hoses.

So not to back track but your secretive spline broaching technique. Would it work to do a slip yoke?
Cool. That will be on my short list of new tools I need to pick up.
Where did you get the fittings from?

All the fittings and hoses came from Vintage air.
This tool will go in our rental category.
Realistically, I will probably never use it again... Or not for a very long time.
