Ur S4: PS Pump Seal Kit?

[James Dupree]

I am looking for a seal kit part number for the PS pump on my 93 S4. I found a part number in the archives (can't find it right now) but World Pac, SSF and my local Audi dealer all show it as an invalid number. It is a combined vane pump for PS and 2 piston high pressure pump for the brake bomb. My understanding is that this pump is the same as a 90 20v uses but is different from every other Audi. Anyone know the number? Mine appears to be leaking between  pump sections, not from the front seal or the high pressure piston caps.

Thanks

Jim
