Watch this video as Lenny explains some of the process involved in what DDP does to create dual feed nozzles for 12valve cummins. Check out more info on dual feeds at: dynomitediesel.com/products/d...
As Lenny said below the flow rate of a 5x.018 they are pretty much unneeded. I personally dynoed a set of 5x.022 Harts injectors like 15 years ago one set was single feed and the other was dual and it was about 75hp more for the dual feeds on a 1300hp motor.
