How carefully did you interrogate the pump? :^)
What I've seen happen is the bearings will wear in the pump to the point where the armature (rotating part) can scrape on the field poles (non-rotating part). This causes a drag on the motor = increased current draw = blown fuse. Usually this does not go on for too long without the pump failing completely.
Unless you've got a wire with an intermittent short, I'd say 95% likely it's the pump. The fact that it's an expensive part also supports this - it's never the cheap parts that fail! ;^)
