Just around. Not EXACTLY number. I am not perfect to memory for everything spec.
Cool, Fuel pressure spec for GM TBI (Throttle Body Injection) is 13 PSI typical and GM PFI (Port Fuel Injection) is 45 to 60 PSI typical for Model year 1993. GM van and truck use TBI, Camaro or Corvette use PFI. I can't help OP. Waste your time.
