A jacketed fuel injection pipe (also known as double walled, twin walled or sheathed fuel injection pipe) is a special type of fuel injection pipe fitted to diesel engines. The pipe incorporates an outer jacket that shrouds the inner high pressure pipe. This jacket is usually metallic in construction and can either be a thin walled tube or convoluted hose. In the event of a burst in the injection pipe the leaking fuel will be collected by the jacket and piped away safely to an alarm device to notify operators of a potential problem.
