gresen fpre rotator preasure

[Caribean_gyro]

I am redesigning my lines for my hydraulic prerotator. I wonder if any know the max preasure the line will handle. also what size you are using, I am using 5/16. But each line weight 4.5 pounds. I have the reservouir up in the rotor head. any reason why not down at the engine base?

Thanks
