Size the to the proper velocity, but also
make sure that there are not any elbow,
valves, strainers, or any turbulent flow
within the last 10 diameters of the hose.
Flange fittings work the best without any
step sizes.
Inside the reservoir one can flare the end of
the pickup tube for much better flow
characteristics.
When Plumbing an inlet line to a pump

Life of oil is shorten in half for every 20 degrees F. above 160 degrees.
It is best to stay at or under 140 degrees at all times.
Think safety also. This does not mean that the oil goes to 200 degrees and
then you cool. It means never let it get above 140 degrees.
Filters also work better with cooler oil.
Geroler motors will fail quickly when the viscosity drops below 70 SUS.
Seals will last much longer.
Running transmission fluid into the radiator actually heats the fluid.
There should be a separate cooler for that fluid and not run into an
engine radiator.
