Autozone lists 2. One for a plant charged system and one for a prefilled. Which one do I need?

 

That would be Factory AC or Dealer Add On AC respectively. Which do you you have?

 

I'd assume factory.

 

I would assume the "in plant" hose...but,
I looked at the AZ site and, yes their descriptions are pretty vague. You might need to look close at your old hose and match up the replacement.

You're looking for the Suction Line. The ones they show all appear to be Compressor Discharge or Liquid lines. The 55782 "might" be the right one. That listing doesn't specify which hose it is.
Edit: 55782 is also a discharge line according to Rock Auto Parts. That's not it either.
I also checked Advance Auto Parts. They only list a discharge hose. It appears that the Suction Line isn't readily available.
If you have the old one, you can have it repaired as ling as the metal tubes are good.

 

I need the one that runs from condenser outlet to the evaporator I think. It's the hose with the orifice tube. I misspoke earlier.

 

Ahhh, that changes things a whole bunch. You need a Liquid Line.

You should still match it up with your old line, but the "Plant Charged" line is likely the one you need.

Some OEM liquid lines had the orifice tube integral to the hose assembly, it sounds like yours did. (I've had folks argue that it NEVER happened in Ford truck applications)
Most replacements don't have the orifice tube built in, check the specs to be sure.
If the replacement line doesn't have the orifice built in, install a Blue or Black .067 Orifice tube into the evaporator inlet tube (it's made to accept one). Slip it into the tube "short end" first. Lube it up with refrigerant oil to help it slide in.

 

When adding oil, which do I use? How much, and do they have a liquid I can pour in somewhere as opposed to the suction method from a can?

 

I added some stuff to my last post. Have a look.


What refrigerant are you using? Why are you replacing the hose? What has been done to the system up till now? What is wrong with the system that you are "fixing" it now?
The oil that you use depends on the refrigerant.

 

A/C Was working, but not cold enough. I added refrigerant, R-134, until it was at the proper level. Went for a drive and it blew the high pressure hose coming off the compressor.

Replaced hose, and decided to replace the orifice tube and the accumulator. While replacing orifice tube noticed the metal tube part of the hose had been repaired and was no longer straight and the PO had cut down the orifice tube so that it would fit.

Added freon and it leaked out. I'm going to disassemble everything and replace all the O rings along with the accumulator ( which I hate doing since mine is new)and orifice tube, the refill again.

The orifice tube that was in there was blue and it was in the accumulator.

Last time the compressor seemed like it was running pretty dry and was making all kinds of noise until it finally sucked enough oil from the can and it quieted down. I rather not do that again. Lord knows the damage I'm causing to a 25 year old A/C compressor.

 

When the line blew, you also lost much of the oil in the system. You really need to flush it dry and start from scratch. You don't have any idea how much oil is still in there or how much to add right now.
It's kind of like trying to add oil to your engine with no dipstick. Too much or too little oil is bad, but there's no telling how much is there to start with. You also don't know what type since the PO had also worked on the system.

8-10 ounces is the factory spec. Mineral oil for R12, Ester or PAG 100 for R134a. (I would go with PAG 100 after flushing).

 

Are you putting a vacuum on the system before you fill it?
