One inch Pipe or one inch AN hose? There is a large difference.
 One inch hose is one inch but one inch Pipe<[tube] is really about
 1 3/8 inch with close to twice the area and flow.

 IMHO one inch hose is a bit marginal. I am going to use Wiggins
 couplings like Bill Schertz  and Continental uses on their liquid cooled
 engines with 1 3/8  OD tubing.

By the way, 1-1/4" Aluminum Tubing just fits in the water pump inlet, and can
then be welded to the casting. That is what makes the transition from the ~25
degree angle to the vertical on my set up.  All the rest is 1-3/8" tube.
