When plumbing for the fuel rails for an aviation conversion, are they plumbed in series or parallel? And if in series, is the primary rail plumbed first?
Patrick,

This is likely worth what you pay for most interweb info, but here's my opinion:

It's just a fluid distribution system; not unlike an air intake manifold. Ignoring the 'ram air' tuning aspect, all you need from an un-tuned intake manifold is the ability to deliver the same amount of air to each cylinder. Same with fuel. If the 'plenum' (delivery tubing) is a lot (sorry that isn't quantified) bigger than the sum of the areas of passages in the injectors, and the tubing doesn't dead-end directly into the last injector in the line (look at the log style intake manifold on a VW based a/c engine), then who's on first shouldn't make any difference.
