I do not see it working since the 1999 has a spider type injection and requires around 60 psi of fuel pressure vs. the 1992 which is throttle body injected and requires 9-13 psi of pressure. So I do not see it working unless you can remove the intake assembly and make the 1992 intake with throttle body injection fit the 1999 engine assembly. If it does not fit then it will not work.
