FWIW, before installing an Exa-Pump, bench test the bitch. I got mine all the way installed and the damn thing didn't work when I put power to it. The bearings or gears were seized up in it. I had to pull the oil lines back off and leverage the gears a little to get it to finally break loose. 10:30 at night and having to drive it the next day is not the time to find out there is something wrong with a brand new $350 pump. I'm calling them tomorrow.
