Maybe the link pipes across the devide to the other pump that's fitted on quattro cars, as it has the prop, they split the tank between sides & this has 2 pumps linked.

If yours isn't quattro then of course this wouldn't be used, but also you shouldn't have that on a new pump anyway if it's the correct one for your car.

Hi yes it is a quattro, I didn't know there were two pumps? there was no connection to the old pump i took off?
 
Maybe the C5 had a different design, I'd have to check etka & elsawin, as I can't recall but most Audi's I've worked on quattro split the pumps across, if yours didn't have the split then guess it's not the same.
