Plug other side of regulator and return out of bottom as normal. I was thinking I could reduce down from -10 main line to a -8 and feed rail and go to reg. with -8 as to were before i was going to run two -6 lines. Would this not be the same as feeding each rail?


What is the in/out threads on your rails? 3/8"NPT?



If you only feed one rail with fuel, and "loop" out the opposite side to feed the other rail, you will be limited to that rail size fuel volume to all injectors. Not exactly sure the limits of a series (looped) set-up, but I'm thinking 500-600hp would be close. A parallel feed (split -10 into two -6's) is highly recommended for the higher power levels you want to achieve. Do not cut corners here or you will be sorry later. Ponies are thirsty, let them drink.
