The fuel pressure for a 2000 Chevrolet Silverado 1500 varies slightly depending on the engine. You'll need to consult your owner's manual or a reliable repair manual specific to your truck's engine (e.g., 4.3L, 4.8L, 5.3L, 5.7L, 6.0L, etc.).
There's no single answer. The pressure will be specified in PSI (pounds per square inch) and will likely be in the range of 40-60 PSI, but again, check your owner's manual for the exact specification for your specific engine.
