One mechanic replaced a ruptured fuel line, inserting a section of rubber hose in the line. This was on an older truck with a vacuum fuel pump. Whenever it reached 45 miles per hour the truck died as the fuel line collapsed under vacuum.
On an Escort, a mechanic replacing a worn fuel pump broke a filter tip off the pump. The tip traveled up the fuel line lodging against the entrance to the fuel injector system. It took two weeks and $900 to figure what the hell was wrong with the engine.
