The fuel pressure for a 1994 S-10 Blazer varies depending on the engine. You'll need to consult your owner's manual or a reliable repair manual specific to your Blazer's engine (e.g., 4.3L V6, 2.8L V6, etc.). These manuals will give you the precise specification.
A general search online might give you estimates, but those are not guaranteed to be accurate for your specific vehicle. Using the wrong fuel pressure can damage your fuel system. Always refer to your vehicle's documentation for the correct information.
