Fuel pressure regulators, was Re: Fuel pump questions

[bruce plecan]

Maybe I should have asked this first, are you talking about the FPR for
the injectors, or for a seperate fuel system for when the NOS in on?.
If your running one pump, and two metering systems, I'd recommend using
a large difference in system pressures, and two return lines.  Sometimes
if the NOS step isn't too large, they use the NOS to hammer the FPR,
in it's vacuum reference line to just run the pressures as high as 
possible.  I'd use a fuel pressure guage on both to make sure one wasn't
robbing the other, or that you're exceeding pump capacity.  While that
-10 looks large, you have a BIG hole to fill when the NOS fuel solenoid 
trips if you're running a big NOS, and it's better to have too much 
fuel around, rather than not enough, and have it sneeze.
