Don't have any pictures handy at the moment, but what I did was install my offending pump in an old, disused, steel AT case. Just ran the wires and water lines out of all the old connector holes, it substantially cut down on the EMI. Sadly, most but not all.
I was reading some time back about somebody that was using a conductive spray-on product to acheive the same shielding effect. Is that somebody around here?
