(1) Metal cap that fits over the fuel injector to secure it after placing it in the fuel rail.

This cap fits on the new style (93+ NA or 95+ TT) fuel rails that support the pintleless injectors.

Sold individuallyy.

The caps for the early style fuel rails are different, but we have plenty of used ones available.

There are also insulators between the tops of the injectors and the fuel rail caps (which are different between the old and new style rails) available separately here on 300ZX.com.
