No, not necessarily.  But it may be (in the older systems) that the
pressure regulator (under the bomb) is the real culprit - not the pump.

I've just been looking at a WR ur-quattro that's gone through three
pumps in 3,500 miles.  I think the problem isn't the pump - I think
the pressure regulator isn't opening a valve when it should and the
'back pressure' up to the pump is destroying them.  There's no
pressure regulation in the pump itself - it's all external.

What happens to the pump if the external system backs pressure up?
