Question on Injector Seals

[silversup]

Hey gang,

I have a question on the injector seals. I have a decent vacuum leak where the rail injectors meet the manifold. My 2 o rings around the injectors are seal well. I checked for the leaks. I understand there is a third o ring at the base of the injector and a grommet where the rail meets each portion of the manifold (ordered from yota).

I am wondering which causes the vacuum leak in this area? The small 3rd seal or the grommet? Figured I would ask while im waiting.

Thanks

If the vac leak was around the injectors it would be the grommet that surrounds the injector nozzle and rests in the intake manifold.
