Bzzz...wrong 
It depends on if the vac line is connected or not...with it connected, 30 psi is max. here's what the TSRM says:

40 psi with vac connected is going to cause a rich misfire.

^jdub i think you might've solved my problem.. how high will my afr go when i get this rich misfire?
Rather than start a new thread, I have a quic k question. How much fuel pressure is safe for a 255lph pump, afpr, and 550cc injectors? Reason I ask is because I am running MaftPro, and I am having some fuel cut issues, so I would like to turn up my fuel pressure and scale the AFM back a bit more. Is there a general limit for no vac fuel pressure I should watch out for? Thanks.
The instructions with my walbro say if flows 255 lph at 100 psi? So id say 100 psi is in the neibourhood of safe, but there would be no need to ever run that high,
Just because it has the capacity of flowing 255lph @ 100psi doesn't mean your injectors work properly at the pressure. The regulator is there so that you can REGULATE the flow to the injectors. Spec for the stock injectors will never change with a new fuel pump, therefore use the stock pressure listed in the TSRM.
