What should fuel pressure be on 1995 blazer?

The fuel pressure specification for a 1995 Chevrolet Blazer depends heavily on the engine. There's no single answer. You must consult your vehicle's repair manual or a reliable online resource specific to your Blazer's engine (e.g., 4.3L V6, 5.7L V8, etc.).

These resources will provide the correct fuel pressure specification, usually given in pounds per square inch (PSI) at a specific engine speed and operating condition (e.g., idle, key-on engine-off). Trying to use the wrong pressure can damage your fuel system.
