Zusammenfassung:	A low cost method for manufacturing and aligning the upper and lower guide members in a fuel injector reduces manufacturing cost and improves durability. The method teaches the use of an alignment tool to axially align both guide members before the guide members are rigidly secured to the valve body of the injector. The dimensional tolerances on the guide members are loose with the sole exception of the alignment aperture which is closely held.
