Fuel: Parallel vs. Series

If your lines are -6, but your rail is -8, why not just get a male/male fitting with -8 threads on one side, and -6 threads on the other?

I have mine wired in series. Could this be the reason my afrs lean a bit when my secondaries kick in? I can see in the log, when duty cycles drops(secondaries kick on) it spikes a couple of tenths of AFRs. I run 40psi base fuel pressure with ID1000pri and ID2000sec injectors fed by Aeromotive stealth pump. I've been wanting to sort that out, as im not sure if it is a tuning issue or not. I cannot currently log fuel press. im working on it.
I was tuning 15U's car two weekends ago and I noticed his did this same thing. I dropped the crossover percentage from 40% to 30% and dropped the Ms to I think .05 and the problem went away.
It was occuring exactly at 40% where the secondaries came online.
The way this works is the secondaries and primaries ramp together given the time duration and the percentage. I don't see a negative to dropping the Ms time delay to almost nothing outside of a little overshoot, but I have yet to see the overshoot?
so try dropping the overlap time value......leave it at 40% and see what happens. I bet it goes away, if not drop the percentage where it ramps the secondaries up.
The settings are on the "settings 5" page.

I'm no expert, but that drawing looks like it's just begging for trouble.. I may (likely) be wrong, but it looks to me like the Primary rail is going to see a majority of the fuel, and the secondary is going to get less than it needs/wants.
If your lines are -6, but your rail is -8, why not just get a male/male fitting with -8 threads on one side, and -6 threads on the other?

also this way i only need to buy two -6 to -8 male to males.
Your concern regarding one rail getting more pressure than the other concerns me. I was thinking the same thing, but then thought if the pump and regulator are doing their jobs then pressure across both rails should be the same? I would be interested to hear others opinions on this as well
