      Dry sump plumbing question

      My new dry sump pan has 4 -12 pick-ups (my old one had 3) and my pump has 3 available -12 scavenge stages for the pan. It has two more stages that are used for the lifter valley and the heads. It's a road race pan with 3 pick-ups on the passenger side (front, middle and back) and 1 pick-up on the driver side back. The lifter valley is sealed off from the bottom of the motor and the rods have EDM'd pin oiler holes to help make sure there is oil for the pins and rings.

      My initial thought was to run the driver side rear and pass side middle and front and then cap the pass side rear, but I could "T" a couple together too.



      So here is my question: Am I better off to "T" two lines from 2 pick-ups together to one stage or is it better to cap off one of the pick-ups and have one dedicated line to each pump stage?

      Thanks

      I'd cap the middle pan pickup... and be done with it.

      Thanks. That makes sense. I'd be good for accel or braking from the front and the rear and with two connected lines there is always the risk of only pulling from one pick-up.
