Thats no Moon, Thats a space station!
Yup mine goes for 10mins or so everytime you turn on the ignition (engine does not need to start)
Quick warning to anyone wanting to service their pump, my original one was leaking so bought a cheapo second hand one off ebay for £20. It was defo in better condition than mine so put it on and its ok so decided to try and clean up my old one as a "backup" The 4 screws are a pain in the bum to remove as they become one with the plastic casing through corrosion and the heads snap off very easily!
I managed to hack my old one apart with a hacksaw in the end and now have some bolts holding it together if I need to use it again.
