I also discovered that the a/c line ( 1 side only ) was broken at the fitting , looks like it just snapped off. Could this be welded again? Also, the bracket that holds the lower section of the a/c lines that run to the front of car is loose and seemed to have had some type of rubber groumet that helps it fasten to the body. Does anyone know where to get a new one? Should I just buy new lines? This is for an '88 coupe

It's possible to have the hose connection repaired but it may not be worth the cost. A replacement at GMpartsdirect.com is $76.04.

edit: revised image, might not be used on 1988 2.8L.

You could have it welded, but the system is under alot of pressure on the high side at times. Best bet is to buy one.

Spark... thanks for the numbers. need one of those myself.

TejasFiero,
If it was leaking thru a crimp fitting, like mine is, you could get it repaired easy enough thru many AC and some hydraulic shops. I just haven't bothered.

being you broke the aluminum I would replace whatever broke. Welding the assembly shown above probably won't last long as that is the most abused hose assembly in the entire system.

You should also check the engine mounts and read the torque strut article in my cave. Especially if you have an automatic transmission. Breaking that hose assembly is a sign that the engine is moving way more than it should be.

One important warning for everyone... If that new assembly above or any other rubber you buy is using the original type of hose, and there is a real chance it does, you do not want to put R134 into the system. R134 will go right thru the R12 hose. It doesn't do that on used hoses because they are soaked full of the old oil.

Normally I believe all the new barrier hose for R134 is marked but I don't know if it would have been used in parts for an older car. Especially a part used in a tiny list of cars. These hoses may have been in inventory for years.

ACDelco reports the hose above used only on the following Fiero models:
1988 PONTIAC FIERO L4 2.5L 2474cc 151cid GAS FI N Engine VIN = R
1987 PONTIAC FIERO SE L4 2.5L 2474cc 151cid GAS FI N Engine VIN = R
1987 PONTIAC FIERO SPORT L4 2.5L 2474cc 151cid GAS FI N Engine VIN = R
1987 PONTIAC FIERO L4 2.5L 2474cc 151cid GAS FI N Engine VIN = R
1987 PONTIAC FIERO GT V6 2.8L 173cid GAS FI N Engine VIN = 9
1987 PONTIAC FIERO SE V6 2.8L 173cid GAS FI N Engine VIN = 9

Unless you can confirm the item uses the new Barrier Hose, you have two options.
Use R12 or have Barrier Hose installed in place of the R12 hose.
