Here's a list of part numbers for seals when your 603.96 IP turns into a sieve:

004 997 46 40 = bottom cover seal
001 074 37 80 = side cover seal (aluminum cover, different seal for steel cover)
000 091 17 80 = lift pump seal
010 997 56 48 = shut off actuator seal
001 074 43 80 = rear cover seal
013 997 81 48 = ELR actuator seal
013 997 09 47 = input shaft seal (who would know this is leaking???)
012 997 83 48 = front seal
123 304 00 60 = VCV seal
N 007603 018100 = RIV plug crush washer (I think, diagram's not clear)

I didn't see a part number for the control rod sensor connector which is just as well since the IP has to come apart to replace that seal... and each one I've seen leaks!

I didn't see a part number for the shut off lever shaft seal.

Crush washers for fuel supply and return lines:

N 007603 012405

Crush washers for lift pump line:

N 007603 010100

While the IP's out, good time to replace the thermostat o-ring:

011 997 39 48

gsxr has a Bosch parts list with some of these seals - http://www.w124performance.com/images/OM603_injection/Bosch_IP_parts_list2.doc There's a parts diagram I can't make sense of due to poor resolution.
