Where is the fuel pressure relief valve on a 1995 Chevy Z26 Beretta?

The 1995 Chevy Beretta Z26 doesn't have a fuel pressure *relief* valve in the same way some fuel systems do with a readily accessible, separate component. Instead, the fuel pressure regulation is handled by the fuel pressure regulator, which is integrated into the fuel rail itself.

Therefore, you won't find a distinct "fuel pressure relief valve." The fuel pressure regulator on the fuel rail *acts* as the pressure relief, returning excess fuel to the tank when pressure is too high. You'll find it located on the fuel rail, usually near the intake manifold. It's often a small, diaphragm-operated device. To pinpoint its precise location, you'll need to consult a repair manual specific to a 1995 Beretta Z26 with the appropriate engine (likely a 2.4L Quad 4 or possibly a V6 depending on specific trim).
