Orifice Tubes
When deciding which orifice tube you should use, remember that color is important. Orifice tube colors identify orifice diameters. Substitution of different color orifice tubes will not work For example, a white orifice tube cannot be substituted for a yellow or red orifice tube for blue in a Ford. Always follow the manufacturer’s recommendations for the exact color and fit.
