Fuel Injector: Installation
- Install fuel injector(s) into fuel rail assembly and install retaining clip(s).
- If same injector(s) is being reinstalled, install new o-ring(s). Two different o-rings are being used. These can be easily identified by color. Install black o-ring at intake manifold end of injector. Install red/rust colored o-ring at fuel rail end of injector.
- Apply a small amount of clean engine oil to each injector o-ring. This will aid in installation.
- Install fuel rail. Refer to the appropriate Fuel Rail Installation in this article.
- Start engine and check for fuel leaks.
