Vacuum leak from fuel injector
A couple weeks ago I replaced the intake manifold gasket on my 2000 Altima. Since this was my first time working on a Altima I pulled the fuel rail from the car. After I replaced the intake gasket, I now have a vacuum leak from the injector down at the intake. I used thr Fel-pro kit HS9942 PT-1 that had the fuel injector insulators. These insulators looked more like an o-ring vice the flat insulators that I removed. I can get the car to run correctly if I install the new insulator along with the old insulator. Or if I removed the plastic spacer (fuel tube spacer) from the two mounting bolts on the fuel rail. I have order new insulator 16636-5E512 from Nissan and still have the same vacuum leaking problem. I am mounting the fuel rail as follow: Intake manifold, fuel tube space, fuel rail and bolt. Can anyone help me resolve this problem.
