97 e225 vro2 rebuilding question

[jetblue319]

hello,
i got vro2 fuel pump rebuilt kit, with factory parts. i noticed two O-rings not mention in installation instructions but shown on part list.
a very small blue o-ring and a large brown o ring #8. the brown o-ring looks like it too big to fit behind part #7. is the small blue o-ring for the part #13 oil piston? and anyone knows if the vacuum p***age o-ring is replaced during the rebuilt? i cant load a attachment its not letting do so sorry

thanks for any help
frank

I don't have the answer to your question hence my hold-off on replying. Hopefully you've already received a answer elsewhere. The usual reason for refusing an attachment or picture upload is the size of the photo. If so, scale it down to about 1000 pixels.

ok will do so on photos,, i chatted with the vendor of the fuel pump rebuild kit. the oil piston oil ring only comes as a whole unit (#13) and the vacuum oil ring does not come with any kit. thank you for your help.
