Hello, here is what I have. CAUTION: Do not attempt to remove the fixed orifice tube, it is an integral part of the liquid line. When a new fixed orifice tube is required, a new liquid line or an orifice tube replacement kit must be installed.
Line & Tube Assembly Replacement
1. Discharge refrigerant from system.
2. Disconnect refrigerant line from condenser outlet connection. Disconnect the line at the evaporator core using the proper spring lock coupling tool, Fig. 2.
3. Route new refrigerant line and integral fixed orifice tube, with the protective caps installed.
4. Remove protective caps and connect new refrigerant line into the system using new O-rings lubricated with refrigerant oil.
5. Leak test, evacuate and charge refrigerant system.
Orifice Tube Replacement
1. Remove refrigerant line from vehicle.
2. Identify location of orifice tube by three indented notches or a circular depression on metal portion of tube.
3. Note angular position of ends of liquid line for assembly reference.
4. Cut a 2.5 inch section from tube at orifice tube location. Do not cut any closer than one inch from start of bend in tube.
5. Flush out two lengths of refrigerant line to remove any contaminants.
6. Lubricate O-rings with clean refrigerant oil, then assemble orifice tube kit to line. Ensure flow direction arrow points toward evaporator end of line and taper of compression rings is toward compression nut. When properly assembled, the inlet tube is positioned against the orifice tube tabs.
7. With tube hex nut secured in a vise, torque compression nuts to 65-70 ft. lbs.
8. Install liquid line using new lubricated O-rings.
9. Leak test, evacuate and charge refrigerant system.
