I have a local place that makes hydraulic hose and he is an expert brazer.... he could cut the end off of that rail and make any radius bend you need.
This may be hard to see... however it is a stock fuel rail being fed from the back driver side with -10AN fitting brazed on.... then the original feed is actually the return. There was also an additional crossover tube added..... to the quick glance it looks stock... but it does support 1400hp+. This is my other RX-7..... 88mm turbo LS9 1/2 mile shootout car. Does mid 190's with total lack of traction.
