Most Common Rail Injectors are Bosch or Siemens

Are your Common rail injectors Bosch or Siemens?

The picture above should help!...notice the difference in the  shape of the plastic tops....Bosch has bleed-off nipple socket (stainless steel)  at the very top of the injector

Peugeot, Ford, Volkswagen....all of these manufacturers have fitted both Siemens and Bosch equipment ..e.g. some Peugeot 205 have Siemens  some Bosch
