If it gets loud enough to be annoying or worrisome, the pump that fills the main pump canister (pre-pump) may be going bad. On mine, an '89 SPG, the buzzing started to sound a little "raspy." I pulled the pump assembly and saw that the pre-pump was so bad that it had been dropping aluminum filings down into the filter screen.
Replaced it with a spare I pulled from an '88 9000 and there was one less noise to be concerned about.
