Comentarios: Per Deutz they used 4 different series of fuel injection pumps on our engines. All engines will only have one series of fuel injection pumps on them, but the customer must verify which series they have before ordering. The series of fuel injection pump can be determined by looking on the fuel injection pump model plate. (Note: Customer will have series A, B, C or D marked on the model plate.) The fuel injection pumps must always be replaced with the same series that where originally on the engine.
