IDk about your fuel pump, I have the walbro 255LPH and if I remember seeing it correctly Mine is set at around 43psi at the FPR. Again Im not sure but either way my setup isn't stock anymore I have 740cc Injectors and Z32 MAF. I would just upgrade your fuel pump to a walbro 255lph to be on the safe side and if you ever decide to upgrade you'll already have a good pump in there.
