Under hard acceleration, I have been hearing the fuel pump (at least I think its the fuel pump.. the thing in the back :smile:) making a high pitched whine/squeal.

It happened today between 1 - 2 and 2 - 3. My Impala used to do this also, but I never had a problem with it.

Is this normal? I seem to think that under hard acceleration, the pump has to work harder to get the fuel to the Injection system, but it is still a bit unsettling.
