Bosch mechanical pump. Injector has a line that screw on top of injectors that distribute fuel. Just sit an idle no smoking. Just a little skip or miss. Try to drive it is very sluggish till it gets going ,if I hit a hill it is like I turned the engine off.
I have a 6.6ford diesel the brizilian one. It is misfiring on the number1 cylinder. New injector has been installed and a compression test. 1992 model f 700 . 171000 miles. Fuel is reaching all injectors.
