Hi Folks,

Just building the fuel rail for my project and I'm a bit confused about =
the regulators.  I have a external pump with a regulator just after the =
pump.  Are there any real issues with just uning this regulator and not =
having a return line ?  Many setups I have seen have a secondary vacuum =
controlled regulator running to the return line.  As I'm unsing this =
setup in a race car with a fairly agressive cam I would have thought =
that the vacuum regulator would cause more problems than helping?

Thanks,

Mark S.
