I found this thread that suggests 3 psi up to maybe 5 psi.

ok guys so the fuel pump i got is a 2-4 psi
but is causing my carbs to over flow and lots of gas come out of a hose that goes underneath my bike
would that be the pump ? or something with the carbs ?

[m-power1989]

lots of gas come out off this hose (not my actual carbs)

Sounds like one of two things, either you got a defective pump that puts out way too much pressure (not too likely) or your carb float valves are stuck open. You may be able to unstick the valve or valves by tapping on the side of the carb, or else it is time to pull the carbs. A carb repair kit will include the valve plungers that have a rubber tip. this part may be shot after all these years. Good idea to check your oil to see if it is gas contaminated. Drain it if it appears too full.

Float might be fine but the needle valve is leaking. Only way I know of for fuel leaking from the overflow is the inlet valve to leak or too much fuel pressure causing the valve to leak. Check fuel pressure.
