That is correct.  There SHOULD be a kit with check valves to be installed in
the truck - when replacing the valve.

> I posted the attached note last week.  The only response I received was
that I should check with my dealer because there had been a service bulletin
or recall.  I talked with the dealer's service center today.  They said it
is a bad Switching Valve between the two tanks.  Does this sound right?

I'm having a bit of a problem with my truck (again!)
it seems my oil pressure has decided to drop
but the way it does it, I find weird.
The engine will run fine with all kinds of oil pressure until the temp gauge
tops the 3/4 mark
then about 3 mins of running at that temp, the oil pressure drops down to
nothing... when I rev the engine, the oil pressure goes up.
I'm totally stumped on this, because it is a brand spanking new pump....
Any help is appreciated
