Fuel pump sound from engine bay?

[Majindan]

I turn the key to on, I hear the fuel pump run for about 5-10 seconds then a audible click almost a clunk sound from around the front passenger side of the engine bay. Is this normal?

No starting issues, fuel pump replaced about 2k ago.

I have the same. From what I know, it's the brake booster. Starting in '01(?), they went to an electric pump that builds hydraulic pressure for the brakes.

Ah so THAT'S what that noise is. I've been wondering that for a while too, and thought it was the fuel pump as well, but thought it was strange that the noise came from the bay.
