Bob, I used AN-16 SS for my coolant system. But, were I to do it over, I
would buy good quality radiator hose and change it every two years. Save
some weight, aggravation and one heck of a lot of money.

Right on. It says re-scheduled. Too bad it didn't get here today. I
don't
remember when it was originally scheduled, so is it early or late? I
should
get it tested next week though. (Rusty sent me his Craig-Davies pump to
measure on the same setup I used with the WP136's)
The hardware store had 1 1/4 fittings and 1 1/2 fittings so I got the 1
1/4.
Maybe I can wrap enough tape around it to get a seal since the pressure
isn't
much.
I bought some Earl's Pro-Lite 350 hose from Summit. It is a nylon braid
and
fits the Earl's reusable swivel ends. It's good to 300 psi and 350 F.
It's
also a lot more flexible than the hoses I had made. Am I going to lose
much
reliability by using this instead of the stainless steel braided hose?
The SS
hose has a better pressure rating, but both are way over rated for what I
need.
