AutoRide Operation

I am wondering if there are any Chevrolet techs on this board that could tell me if my AutoRide is operating correctly. Should the pump run for a few seconds eveytime I start up the vehicle? When I say "everytime" I mean after it has sat for at least a half hour or so. I, not knowing too much, would say this could be normal but I think that when we first got the truck it didn't pump everytime you started it up. What I am saying is, do I have a leak?

Mine does the same thing and has ever since new

I appreciate the reply. I figured it might have always been that way but wasn't sure about it. I am OCD about leaks and stuff so I would have had to fix it or get them replaced if I had been told it could be leaking. Thanks again.
