Well, the only mention I see about the arrow is in the troubleshooting section. I have it installed in the right direction. It still is behaving in an odd manner. The accusump will not fill unless the switch is OFF. (yes I checked the switch with a meter). Once the sump is full it prelubes fine when I turn the ignition on and the accusump switch is ON. Engine fires but accusump does not fill. I turn the switch OFF and the accusump fills. I'm stumpted.
