Robert :
My suggestion would be to start by at least temporarily installing an
oil temperature gauge, to see how hot your oil is getting. The temp in
the pan needs to reach at least 200F, to boil off water and acid. Unless
it's reaching at least 230F, I wouldn't bother with a cooler, and even
then I'd consider adding a thermostat for it, especially if you ever
drive in the spring or fall.
The rubber hoses are fine, IF you make sure they cannot chafe anywhere.
Support every 9-12", and add extra protection anywhere they contact
metal. Make sure they cannot contact any metal edges or corners. Don't
forget the engine moves side to side a fair amount.
However, the metal braid is cheap insurance against what can be a _most_
unpleasant failure.
