I always ran a stock fuel pressure regulator, what are you worried about if it bumps it up to 40-45psi at your base who cares.
If you are tuning this thing with an adjustable fuel map you can change it so it runs fine.

Re:Walbro hp 255lph fuel pump
ok but the hp one will be ok right as long as i adjust in uberdata? set the injectors at 450 and fp at 52.. bc of the 10psi increase from the 255 pumps?
correct?
both pumps make the fuel pressure increase just the HP continues to flow after 60-70psi
please correct me if im wrong?

You'll be perfectly fine with that Walbro then. Jeff or anyone else, I'm curious to know what kind of fuel system modifications actually need to be done when reaching high HP like that. What do they swap the stock fuel lines with etc.? Not that i'm planning to ever be able to have 500HP under my *** in a Honda, but it's just interesting to know.
