1) aluminum is lighter, better for o rings.
2) advanced set ups typically delete the filter head line.
i like to run my IP return to #2 cap.
and return from #7&8 to a T.
even with factory turbo.
route them along the back of the intake away from the DP, and you wont have any issues.
1 cap with 1 nipple,
4 caps with parallel barbs
(end or middle, it dont matter, but middle barb will cool the entire injector with cooler fuel)
3 caps with 90 degree barbs.
just my opinion
