ID 1700 primary injector question

I am switching from a stock primary fuel rail with 850cc injectors to FFE lite primary rail with ID 1700 injectors. Do you need the rubber o rings that go in the side housing like with the factory rail or are they not needed with after market injectors? Thanks

For a easy install you should use the FFE ID adapter inserts.

Yep, you need something there to seal the end of the injector to the engine. if not you'll have a vacuum leak.

The FFE solution looks great, the stock grommets are kind of crappy even on stock cars.
