Where is the orifice tube located on a 1998 E350?

On a 1998 Ford E350, the orifice tube is typically located in the refrigerant line between the evaporator and the accumulator. To access it, you may need to remove the accumulator, which is usually mounted on the passenger side near the firewall. The orifice tube itself is a small, cylindrical component that can be found inside the line fitting. Always refer to a repair manual for specific instructions and diagrams for your vehicle.
