Thanks for the info
Electric motors (in general) take much more current when they are heavily loaded culminating in a HUGE amount when they are stalled. Is your HP pump pumping into a very restrictive fuel system? (Small return for example) It's either that or the mechanical side of the pump side is b*ggered - but then I would expect problems from the engine itself (fuel starvation for example).

PS - I run both pumps from whatever the standard BMW fuse was - as I remember 15A.
