Ferrari Mailing List: Fuel injection parts needed

[Rick Lindsay (rolindsay]

Anyone know the part number of, and a source for, the black rubber bit around 
the injector, as shown in this picture, 
http://www.aubard.us/Mondial/injector.jpg .  The early K-Jets used metal 
screw-in injector holders (as also showin the picture) to keep the black bit 
(and injector) in place.  Later models, I am told, used a pressed-in rubber 
plug.  Advise?

Regards,
