Default Fuel pressure regulator issue

Ok so I'm pretty sure my regulator is shot. Can't get into it at all without it choking up and supudering. Feels like it wants to stall at idol.
H/c/I 5spd 255 pump with 24# injectors. Ive looked into getting a new regulator but don't know what psi I need to be at. Some are at 45, other adj from 35-65.
Any input would be great

Should be about 42psi with vacuum unhooked. 38-39 psi are also good to if you get that. it could be a bad fuel pump if you get low pressures and bad regulator if you get too high.
