Precaution for Handling High Pressure Fuel System

WARNING: This page is about a different car, the 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

High pressure fuel system components are between high pressure fuel pump and fuel injector.
Always release fuel pressure and never start the engine when performing removal and installation.
When removing or installing parts without releasing fuel pressure, fuel may be splashed and, if fuel contacts skin or eyes, it may cause inflammation.
