Do not open the high pressure fuel system without allowing the fuel system to purge. After the engine has shut down, allow the fuel system to purge for ten minutes. This operating fuel system contains high pressure. Exposure to high pressure fuel can result in personal injury. |
Note: Use Tooling (A) to cap tube assemblies, fittings, ports, and any opening in the fuel system in order to prevent contamination.
Note: Do not remove all the quills in order to maintain the alignment of the rail. Maintain at least two quills attached to the rail at all times. If necessary, replace with new quill.
- Remove bolt (1) and the clamp from tube assembly (2).
