What should the fuel pump pressure be on an 02 6 liter silverado?
The fuel pump pressure specification for a 2002 6.0L Silverado is 58-62 PSI. However, this should be measured with a fuel pressure gauge at the Schrader valve (usually located on the fuel rail) with the engine running. Keep in mind that this pressure can vary slightly depending on factors like engine temperature and altitude. Always consult your vehicle's repair manual for the most accurate and up-to-date information.
