These conditions may be caused by a fuel leak at one of the high pressure fuel rail pipe connections that was incorrectly installed during service of another engine component that required the fuel system to be opened, such as fuel rails, fuel injectors, high pressure fuel pump, etc.

 

TIP: The engine fuel feed intermediate pipes must be replaced during any service repairs that require one or more of the pipes to be loosened or removed.

Yeah it's a stainless steel fuel line and fittings. Stainless tubing and compression fittings almost always leak if you try to reuse them. I deal with it all the time on high pressure steam and hydraulic lines. Not worth it.
