Good information. Thanks.

I would set the 555 up between the positive source that feeds either the relay or the buzzer itself. This assumes that the sender does nothing more than provide a ground when there is no pressure on it. The 555 in its simplest form is really nothing more than a "cup" that gets filled up and when it does get full it "spills" over the side, but instead of water it uses electrons.
