There is at least 2 thread on the Pump that includes adding a fuse to the circuit. 
  
When I went to add a fuse to mine I found out the Pump was dead and just left it disconnected. Not so cold where I live so you don't need it.

  He also mentions an auto-resetting "circuit breaker" on the later cars.  Maybe on the 190 (which uses an entirely different control unit), but absolutely NOT on the W126 or W124 from 1986+.  
Having repaired many W123 and 107 pushbutton units and silver control boxes, I've also never seen a fuse anywhere.  Not saying they don't exist on those cars, they did some weird stuff throughout the 1985 year.
