What should the fuel pressure be on an 2002 5.3L silverado?
The fuel pressure specification for a 2002 5.3L Silverado is 58-62 PSI at idle. This is typically measured with a fuel pressure gauge connected to the fuel system's test port. Keep in mind that this is a *key on, engine off* reading. The pressure might fluctuate slightly with the engine running, but should remain within a reasonable range of that specification. Always consult your vehicle's repair manual for the most accurate and up-to-date information.
