Hi everyone, brand new member. I have owned a 91 Ranger Supercab (3.0L V6) since new. I have a Dealer installed A/C system which has worked flawlessly since new. Never added refrigerant or serviced in anyway. The truck has 109K on it and has spent it's entire life in Northern NJ. This past weekend the High Pressure Discharge line/hose from the compressor to the condenser burst while at idle, releasing the refrigerant and oil all over the side of my battery. The line burst,(the underneath side of rubber hose) about 3 inches from the condenser. Here are my questions. Q1) what makes this line burst at that point? Age, problem in another component like blocked orifice tube or faulty high pressure switch? Is this normal? Q2) I have checked online and I'm not locating a replacement discharge line for this model, retail on the hose is about $300, and is out of stock at websites. Should I write this one off or is there hope for my beloved Ranger(actually my wife's and she is in love with this truck!) Looks like the dryer is cheap and available. I don't know about R-12 availability either. Thanks everyone, could really use some experienced advice from those of you who have successfully rebuilt these systems back to working order.
