ETKA part # search?

[doubt at inwave.com (Nate Mellom)]

With all the copies of ETKA I have, of course I don't have it installed 
on my machine. Whodathunkit?

Anywho, can someone run a part number for me?  I'm in need of a fuel 
pump relay for my '84 Audi 4k (1.8 FWD).  The one I have is:
443 907 385c

I'm looking for a cross-application check here, I can't believe it's 4k 
only (not too many in boneyards around here).

Thanks!
Nate
