Subject: noisy fuel pump

> The fuel pump on B. Bones was excessively noisy, so I robbed the almost
silent fuel pump off of Long John.  HOwever, that same quiet fuel pump is
also very noisy on B. Bones.  What gives?  How can it be silent on one bus
and so noisy on another?  Mounting brackets are the same, connections seem
the same ...

Sounds like restricted flow of fuel through the pump (pump is cavitating/air
bound).  Check the fuel filter, and see if there is junk coming from the gas
tank clogging things up.

BTW, the fuel pump is cooled by the fuel, if the flow is restricted it will
shorten the life of the pump considerably.
