87-97 Exp Valve/ Orifice Tubes, Red

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 red orifice tube cannot be substituted for blue in a Ford.

Always follow the manufacturer’s recommendations for the exact color and fit.
