The stock fuel pressure for a 1995 Chevy Silverado varies depending on the engine. You'll need to specify the engine size (e.g., 4.3L, 5.0L, 5.7L, 6.5L diesel) to get an accurate answer. The pressure is also usually specified at a certain engine speed and condition (e.g., key-on-engine-off, idle, etc.).
Consult your owner's manual or a reliable repair manual specific to your Silverado's engine for the correct fuel pressure specification.
