I installed new injectors in my m1008 last night, it fired right up and sounded good. Went for a test drive, pulled over to check for leaks and saw that the driver side rear most injector was pumping fuel all over the manifold. It looks like it is coming out between the injector body and the screw on injector head. Can I use a thread tape or somthing to seal it? I have tried to tighten it up but and cant get it any tighter. All the other injectors are good to go.
