Question by: Harvey E on May 9, 2025, 7:35 AM
got a setup that runs some back pressure, when do i need to bother with a case drain line on this motor?
Answer by: Customer Support on May 11, 2025, 6:37 AM
If you are going to see continuous back pressure over 1100 PSI, plan on running an external case drain line. Set it up so the motor case stays full of oil at all times.
