Been poring over the archives chasing defunct p/ns and obsolete kits, doing my best to determine what I'll need in order to rebuild/refresh my 81 240D's lift pump.

So far:

1.)000-090-02-10-MBZ (2 plastic valves, 2 springs and 2 crush washers)
2.)003-997-82-45-MBZ (Tiny rubber gasket/seal ring)
3.)001-074-22-80-MBZ (lift pump gasket to IP)

Maybe:

4.) 000-090-01-10-M14 OR 1-587-010-532-INT (fuel pump check valve)
not sure if this usually needs replacing...
5.) 0009934801 (Spring behind 30mm nut/ could be the 300d's spring #)
6.) Crush washer or internal gasket (???) for whatever's behind 30mm nut

Anyone done this refresh and able to confirm what parts I need?

After driving, I have noticed some wetness on top of the pump which could be coming from any number of things. Otherwise, no real issues to report, merely preventative maintenance.
