Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
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 (B) 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. Remove one at a time and replace before the removal of the next. If necessary, replace with new quill.
