Default blown a/c refrigerant discharge hose

So after 30ish years the discharge hose finally gave up the grey ghost. Sounded like my truck was shot and suddenly deflated. I have searched high and low for the hose with no luck. I have tried the big stores; auto zone, advance, napa and the dealer. I also tried Nissanpartsdeal.com. The all say the part is no longer made. I tried firestone but they will not repair it either.

Any ideas on where I go from here? There are some junk yards around so I will try those this weekend but I would prefer to purchase a new one and not one that is 30ish years old.

Do I convert to the non Freon unit? Do I just ride out the rest of the summer days sweating?

the part number I have for the hose is:
a/c refrigerant discharge hose assembly
Nissan Part No.: 92490-01G81
Alternate part No.: 92490-83G63
HOSE HIGH


thanks in advance for the advice.

I know there are places that repair the hoses, just not in your area.. sorry no help
the place here is called "all tubes and hoses" 602-253-4507 if you can not find someone closer maybe you could ship it to them??? last resort thing anyway

I once had a car with a similar problem. The A/C never worked anyways but it eventually leaked out all the refrigerant and caused the bearings in the compressor to squeal. You might consider removing the belt that drives the compressor to preserve it until you can get the problem fixed. I ended up just bypassing mine and getting the belt for a non-A/C model.

A junkyard visit might be your best option, or start searching your local Craigslist for Nissan trucks being parted out. While you are there, pull the compressor, too...if you think you have ruined the bearings by letting it squeal.

Failing that, SBJ's suggestion to bypass for now sounds like the best option.

@joetruck, do you know how to upload and post pictures?

I make no effort to learn the AC system, but I know it has several hoses.

Perhaps you can take a picture showing the whole engine, and pointing to the hose that blew out.

There are members here with parts trucks. If you can point out what is broken, someone might have a replacement for you.

It is the high hose from what I can gather from the schematics on nissanparts.com yepee.

There is a bit of a learning curve to it. Once you figure it out, though, you can upload and post your photos all over.

which hose is the culprit? the system stayed virtually the same for the entire production of the D21. the only variation MIGHT be the lines that attach to the compressor. that might be the reason the low pressure line is a 2 piece. #6 is the suction side of the compressor, #7 is the second part of that coming from the evaporator core. #4 is the high pressure line feeding to the drier. #5 is the high side back to the compressor. so it is one of those four that you need.
