Nathan,
  I just went through this and I actually still have a "humming" in the
back...  I had a buz coming from the pump.  Van had 159K on it at the time.
I had the exact same concerns as you and dropped the $160.00 for a brand new
Bosch (not remanufactured) pump.  Put it in and guess what, started to buzz
about 3 days after I put it in.  I do believe that it actually is the way
the pump is mounted, not the pump it self.  I will be putting (as soon as it
warms up around here) a rubber band (from an old bike tire tube) around the
pump to stop the humming between the metal can of the pump and the metal
bracket.  I will let you know what happens...

  Richard and Annemarie
