Hey All:

I am in process of trying to replace the seals in the lift pump of my 95 E300 and I have some questions. The first attachment is the EPC exploded view of the lift pump - I have added in the EPC labels and part numbers. The second attachment is my exploded view of my lift pump - taken off the IP and disassembled. The two don't really jive - in fact, I have only found one o-ring on my lift pump - #276 on the EPC diagram (presumably this is the o-ring for the screwed in fitting that it is directly below it in the diagram but not shown as a seperate fitting). Anyway, the main question right now is - where are these other o-rings? Are all the orings internal to the lift pump, or are some supposed to be visible on the exterior of the pump once you remove it from the IP? Let me know if I need to clarify anything or take any other pics to help explain. Thanks!
