Where is the fuel pressure test port on a 1995 Chevy Beretta?

The fuel pressure test port on a 1995 Chevy Beretta is typically located on the fuel rail. It's a small fitting, often with a Schrader valve (like a tire valve) that you can connect a fuel pressure gauge to. However, its exact location on the fuel rail can vary slightly.

You'll need to visually inspect the fuel rail itself. It's a metal bar running along the top of the intake manifold, with the fuel injectors connected to it. Look carefully along the fuel rail for the small port; it might be near the end, in the middle, or even have a short length of hose leading to it. A shop manual or a diagram specific to your engine (likely a 2.3L or a 3.1L) would be the most reliable way to pinpoint its exact location.

Important Safety Note: Working with fuel systems is dangerous. Fuel is highly flammable and pressurized. Always disconnect the negative battery terminal before working on the fuel system. Be aware of potential hazards, and if you are uncomfortable performing this task, have a qualified mechanic do it for you.
