Which AC line is this?

[Matthew Jeschke]

There's a line leaving the compressor, it goes directly to bottom of condenser unit. It's leaking on my truck and I need to replace it but I cannot figure out what hose that is called? It's a 2001 Z71 Tahoe

Thanks!

Maybe a pic and if you have rear ac would help.What engine do you have assume 5.3-its a single line not a dual at compressor? https://shop.advanceautoparts.com/w...dSearch=2259495&isAllVehicle=false&isFitted=1

It is bottom connection on compressor closest frame. It runs up towards the condenser unit. Not sure if is top or bottom connection.

I have rear air. The splitter connection above goes to fron evap and rear evap.

O'Reilly carries a gasket and o-ring kit for every fitting on our AC systems too.

That's awesome. Yeah I may leave all else be. I rebuild the system not long ago. (minus compressor). I put all new seals, expansion valves, etc.

Ah sheep Sheet beaches hahaha

I installed the line, it was the discharge / suction line. New one is great, no problems with it. However, I thought dang I should probably replace the oriphice tube while I am in there.

I charged the AC with two cans of refrigerant and the low side runs too high. I get 70 PSI on low side. What could cause this? Could it be a bad oriphice tube?

I should be getting 55 PSI on low side.
