I'm contemplating on installing a return fuel system and I wanna get some information on fuel pressure regulators. Anyone know of a thread or site that discusses FPR's? Also which is better to have: a rising rate FPR or a user-fixed one?

If you search using the phrase, fuel return shopping list, you will find a very good list written up by lampchop on what you will need for a complete fuel return system.

With a boosted application you will always want to go with a rising rate regulator.

With a normal fuel controller, you probably want to go with a 1-1 rising rate.
