The fuel pressure for a 1988 Chevy 454 engine typically ranges between 5 to 9 psi when the engine is running. This pressure is crucial for proper fuel delivery and engine performance. To ensure optimal operation, it's important to check the fuel pressure with a gauge and verify that it falls within this range. If the pressure is too low or too high, it may indicate issues with the fuel pump, filter, or regulator.
