Loclines on a closed loop w/OM 4 way and Dart

[lapizzaro]

Will loc lines on the returns of a closed loop cause any back pressure on the OM/Dart? I have 4 returns - 2 drilled and 2 over the back . I am using 1 inch pipes and 1 inch bulkhead and was planning to put single or dual 3/4 inch loc lines on the returns.

Any comments will be appreciated.

Thanks

Back pressure? No, but you will have restriction. One 3/4 is too small to get full use of your dart. You want to at least split it at the end into 2.

I used 8 1/2" lock lines on my manifold that is run by a dart. I could not see using less.

Do you mean use the dual 3/4 loc lines
