Installation Notes and Tips

Clean the injector and rail sealing surfaces before installation. Inspect the injector body and rail for scoring, corrosion, or debris that could affect seal performance. Lubricate new rubber O-rings with clean engine oil or an approved assembly lubricant before fitting them to avoid tearing during assembly. Verify the injector and rail style against the vehicle service information before installation.
