What should the fuel pressure be in a 1996 Chevy truck with vortec v8?

The fuel pressure specification for a 1996 Chevy truck with a Vortec V8 isn't a single number, it varies slightly depending on the exact engine and testing conditions (engine running, engine off). You'll need to consult your vehicle's repair manual or a reliable online resource specific to your truck's VIN (Vehicle Identification Number) for the precise specification.

However, a generally accepted range is between 12-14 PSI (pounds per square inch) with the engine running. This is often measured at the fuel rail. The pressure may be slightly different when the engine is off (and the fuel pump is not running).

Crucially: Don't rely on a generalized range. Find the *exact* specification for your specific 1996 Chevy truck's Vortec V8 engine. Incorrect fuel pressure can lead to serious engine damage. Check your owner's manual or a reputable repair manual (like a Chilton's or Haynes manual) for the correct information.
