Hello Paul,

Does anyone have any experience using stainless steel flex radiator hose?
KMJ Performance carries a 48" universal kit for $57.00.  Any thoughts?

Chuck Dunlap has used it for years.
Pictures are on the front page of the web site.
Did you see them?

Be sure to use Breeze constant tension house clamps.
It is better to use aluminum tubing I suspect but can't prove
it as it should speed the flow of water with less pressure drop.

If you want the best and most reliable long term use tig welded
Wiggins couplings and aluminum tubing also shown on the front page
of the web site near the bottom. These are universally used in airliners
and Formula 1 race cars.

If you use silicone rubber hose and aluminum tubing be sure to bead the tubing.

At 15 psi water pressure and 1.5" diameter water plumping tube there is about
26 pounds of force trying to pull the hose off the tube.

At 30 psi the force is 52 pounds. A 30 psi pressure cap is a good idea to use
as it raises the boiling temperature of the fluid. Absolutely the
last thing you want to have happen in an airplane is boiling the fluid as it will all
be pumped over board.

Send some pictures of your cooling system. If you think you might
not want to be possibly embarrassed ( I would never do that) put the word PRIVATE
in the subject box and I will keep the pictures and info secret. Years ago cooling
the rotary was the hardest thing to achieve but over the past 12 years
that problem has largely gone away due to a sharing of experience on here.
