I found this interesting video:
Basically the fuel hoses get worn by a clamp nut over time, especially after an engine out service, if they are not orientated in the correct way. Over time the nut rubs through the fuel line and you end up with fuel spaying into the engine bay. Not good at all! If you have a F355, make sure you check this, especially after and engine out.
The video also details how a water hose that runs between the fuel lines can get worn through by the braided fuel lines themselves and may rupture. Again, something to add to your check list, I suggest.
