Space ship noise from pump in summertime?
. I know that sounds silly but that is what it sounds like. It doesn't occur if my car sits overnight but if I drive somewhere in the heat, let it sit then start it up again I hear it loud and clear. I was told it is some sort of pump for air or fuel or something? If you know what I'm talking about could you please post a pic of where it may be located. BTW I can hear the noise in the engine bay and as well as coming right out of my exhaust.
