If you have fuel injection, your regulator would be on the fuel rail where the injectors are. Looks like a round piece about 1.5" in diameter and 1" high.

Z31s are NOT carburated. They ARE fuel injected. the fuel pressure regulator is on the front of the intake plenum(the part that has the NISSAN 3000 cover on it). right smack dab in front of you, and on top when you open the hood. it will have three hoses connected to it. One coming off the top, and two on the bottom. there will also be a small sensor threaded into the side(fuel temp. sensor)
