The 1989 Chevrolet 350 TBI (Throttle Body Injection) typically operates with a fuel pressure of around 9 to 13 psi. This pressure is crucial for the proper functioning of the fuel injection system, ensuring that the engine receives the right amount of fuel for optimal performance. It's important to check the pressure with a gauge to ensure the system is operating within the specified range.
