Let us know what brands they were so we can be wary of their pumps. I got a TRW pump many years ago that was supposed to be a HV pump and I noticed when I stuck the oil pump drive in it to turn it before installing it that the shaft could move in and out about an eighth of an inch. I think they put a standard rotor in a HV pump. Glad I found that out before installing it because that means there was that much side clearance in the rotor inside the pump. I took it back and got another pump. I've checked them all like that before installing them from that point on.
