Fuel line routing on top of engine allowed an abrasion hole in a pressurized feed line. The routing of the fuel feed line was too close to the feed line on one of the cylinder fuel injection lines. A 3/8 high pressure line developed a hole and fed fuel to top of engine intake manifold valley. This engine has a turbo charged injection and fuel came incontact with hot componets. The dealer fixed the symptom of the leak by brazing the hole close with metal flux. The root problem of too close of fuel line routing was not addressed, therefore leading to a potential under the hood fire. I do not know if this problem is related to only this vehicle or the 7.3L series motor from from Ford for the F-250 trucks. Secondly, as an aviation repair technician, I do not feel a fix of this type on a high pressure fuel line should be the proper repair action, the line should be replaced. The root cause of the abrasion thru the line should be addressed.
