What are the fuel pressure specs for a 88 GMC 5.7?

The fuel pressure specification for a 1988 GMC with a 5.7L (350 cubic inch) engine isn't a single number, as it depends on the engine's condition and whether it's running or not. You'll need to consult your owner's manual for the most accurate specifications.

However, a generally accepted range for engine running is between 12 and 14 PSI. Some slight variation within that range is acceptable. The pressure should be checked with a fuel pressure gauge connected to the fuel system's test port.

Important Note: The pressure will be different when the engine is off. You should *never* work on a fuel system without taking proper safety precautions, including disconnecting the battery's negative terminal. Fuel is highly flammable and potentially explosive.

Always refer to your owner's manual for the precise specifications for your specific vehicle. If you don't have the manual, you can often find a digital copy online through a site like HelmsInc.com (they specialize in GM manuals).
