You need a boost referenced regulator to do it right, they are not real expensive either.

you need to do a fuel pressure return setup which involves a return to the tank and a regulator plus line and fittings
basically run off the shrader valve on the fuel rail to the regulator then the other port on the reg to the tank

I AM NOT running the stock regulator, though...

60#-ers, Walbro pump, and FP regulator... Stock everything else fuel-related though... For the time-being... This winter I'll complete what I started.
