Re: VW PARTS INC, Viton tip Injectors

["Scott M." <scottmo@teleport.com>]

Mark,

Did you return the injectors after checking the part number
or by visual inspection? You can't really see the Viton
rubber tip, but the Viton injector ends do look
slightly different from the metal tip versions.

According to the Bentley:
The Viton tipped injectors carry the following part numbers
(3.2 bar version, high pressure,  fine thread) Audi # 035
133 551F, Bosch # 0-437-502-043, or OEM Bosch version
0-437-502-044.

(2.5 bar version, low pressure, coarse thread) Audi # 026
133 551, Bosch # 0-437-502-045, or OEM Bosch 0-437-502-046

HTH
