Hi Jerry,

I put a 1.25 inch ID hose on the DC inlet and outlet when I did that
test.  It was tight, but I think 1.375 would be too loose, so I suspect
going much larger than 1.25 probably won't help much.  I used some
white plastic hose I got at Home Depot and heated it up till it was
soft and pushed it on the water pump fittings.

I would keep the pump as near the bottom of the cooling system as
possible.  I plan on mounting my Meziere WP337 a couple inches above
the bottom of my radiators.  Also, the output of the pump should be
higer than the input (per DC instructions sheet).

Using AN16 fittings and Earls ProLite 350 hose will give me an ID of
0.88 inches.  The SS braided hose is the same ID.  At least the hoses
I had made were a full 1 inch ID.  I should get some flow results next
week.

Bob W.
