Relieve fuel pressure.
Disconnect pressure regulator-to-fuel rail hose. Remove fuel rail.
Remove pressure regulator retaining bolts. Remove pressure regulator from fuel rail. Remove pressure regulator retainer and seal from fuel rail.
To install, reverse removal procedures. Always replace the "O" rings. Lubricate fuel rail seal with oil and install in regulator.

Sorry, my mistake. That was for wrong fuel system..here is the correct procedures for your TBI system. You will have to remove the throttle body cover, the regulator and body cover are serviced together only.
