When designing a fuel system, I go by the "30% Rule" When pumps are tested and rated they include specs for voltage vs. pressure. They don't account for g-force and inlet/outlet restrictions and plumbing decisions.
I would look to run hard feed and return lines attached to the frame and protected as best as possible. At the engine area, you'd want to switch to a short flexible line for chassis to engine coupling. The best advice I can offer is to use quality 100 micron pre and 10 micron post filter. I'd look at a Walbro GSL392 inline 255lph pump mounted in a gravity position as to induce good inlet flow.
The rails can be done with a less expensive rail mount regulator like Holley's 512-500 attached to a set of their universal rail kit like 534-79 machined to fit your application. You can also run a remote mounted regulator which is abit more expensive along with the addtional cost of fittings. We also have to take our customer's budget and needs into the plan. Hope this helps
