I have an 1988 C1500. It was converted to R134A a while back and the schrader(sp?) has gone bad. The guts have pushed thru the stem and are not catching any of the threads on the inside. It the line that comes from the condensor to the evaporator, with fitting for putting in the freon. I cannot locate that line anywhere. I have been to O;Reilly's, NAPA, where we talked about having one made out of black #8 hose and appropriate fittings. Also, went to LMC Truck but they dont have one for that year. I even purchased a new one from a supplier with the intent for finding a good welder who can remove the old one and helioarc (sp?) the new part on.

I am going to try a local junk yard next to see I can source the part from there.

Any body have any other sources for this hose? I went to XLParts today and talked with a few guys there over an hour trying to even find the correct part number.

Any help would be appreciated.

Pay the piper and have it made. A used one is going to be a bigger problem because of its age.

Depending on where you are, there may be a specialty shop near you that custom-makes A/C lines. We've got one here in Houston but that is kind of expected.

If I'm reading you correctly (OP) this is the line where the orifice tube sits, right before it goes into the evaporator core? That's the 88-early 90 design. In 90 they changed to the orifice sitting in the line that is part of the condenser. I suspect* if the later style is what you're finding available, it would be no big deal to change to the new style condenser too, except of course the cost. Compare that to having the custom line built. The condenser is about $60-$200 depending on what brand you trust.

*this is an assumption; I have not tried this modification. not certain if the fittings are the correct sizes etc. comparing part #'s on 88-early 90 evaporator core vs. 90-93 may shed some light.

I had a hose blow on my '94 Sierra back in June 2016. I went the same route you are going and found a guy that would make a new one for $340. I decided to try a junk yard and I found one at the first place I went. I paid $40 for it.

In my case the original blew because it was rubbing the wheel well. I reinforced the hose in that location and checked the new used one closely before I bought it and it's still working well today.

I found in a junkyard here locally in north Texas. Works great! I replaced the condenser also, and all of the seals except for the AC manifold, didn't buy them. Well guess where it is now leaking?! Yep you guessed it the manifold area. I pulled it off the those metal washers with rubber seals are pretty flat and didn't want to seat very well. Have a pretty good mess right now. Order those new seals and will install tomorrow when they arrive.

Pretty good learning experience for me, got some new cool tools too! Much cheaper than the quoted price of $500 to do this work too! Will use these tools to replace the condenser on my son's 2015 Silverado. It is leaking in the top corner on the drivers side.

I understand there is a tech bulletin out concerning the vibration of the lines coming from it to the engine. Anyone know more on this?

Thanks for the input.
