Just put in an order for one of the Fluidyne's, but it looks like I'll have
to do some modification to make this fit, but it shouldn't be too extensive.
About pulling the valve, I was just thinking that since my oil outlet is
out of the bottom of the front iron, I could plug this outlet into the
front cover completely as Lynn has suggested if I didn't need to have the
valve.
  I see that the exit side of this cooler has a bung for a pressure sensor.
I think I'll move my pressure sensor down here so that I'll be measuring
pressure before the filter the way Mazda intended.

Todd...    too broke to say anything witty.... :(
