    It’s almost unbelievable that the pump will pull a vacuum with those four holes. I could see it working if the holes were on the pressure side of the housing; but with the even spacing, it seems like at least one of the holes would be on the vacuum side. I don’t do much with Scott Atwater but I do a LOT of Mercury automatic transmission stuff; so nobody gets the importance of pump vacuum more than me. Man, I certainly don’t get it!

    Long live American manufacturing!
