Where is fuel pressure regulator located on a 1995 g20 Chevrolet van?

The fuel pressure regulator on a 1995 Chevrolet G20 van is typically integrated into the fuel rail. It's not a separate component like on some older vehicles. You'll find the fuel rail on the intake manifold, and the regulator will be part of that assembly. You'll likely need to remove some components to access it properly, possibly including air intake parts and possibly even some fuel lines. Consult a repair manual specific to your 1995 G20's engine (e.g., a Haynes or Chilton manual) for precise location and removal instructions. This will be far safer than relying on general advice.
