It’s my (frequently faulty) understanding that our fuel supply system is a returnless or deadhead type, and that the fuel rail’s pressure is regulated by the fuel filter’s internal regulator. If the pump is able to supply sufficient pressure – and its commensurate volume during peak load/RPM/boost – from where are the gains you speak of being derived?
Would you kindly enlighten us with the specifics of your “dynamic compensation” arrangement? TIA.
If this is the case (and I think it is) adding a returnline is fairly simple. SRT-4 Neon guys (including myself) do it all the time. Adding an AFPR to the test port on the rail and running a braided line back into the tank or filler pipe is all that is needed. Plus modifying the stock regulator to push continues pressure.
EDIT~ Screw it, Ill go play with the car next weekend and see what I can do for an AFPR.
