8N power steering

[azgoldust]

Adding power steering and an FEL to my old friend and have a couple of questions.
1. in normal hydraulic runs, using 3/8 hose, what size rigid tubing is required?.

2. does the 3 point lift hydraulics flow enough for power steering, I will be using
a pair of 1.5 bore cylinders on the drag links with a dedicated valve and lost motion device
to actuate the valve

I have also mounted a 3 GPM pump driven off the crankshaft which I plan to use
for the FEL or should I reverse the two sources.
The pic is a mockup of the pwr steering before I clean every thing up
for the finish.
