The Fuel Distributor is the heart of the K-Jetronic and KE-Jetronic fuel injection system used on many European cars. Mercedes Benz, Porsche, BMW, Volvo, Saab, Volkswagen, Audi, Peugeot, DeLorean, Ferrari, and Rolls Royce have all used this system. The CIS system has very few moving parts and is very reliable unless contaminated by chemicals that attack the o-rings, old fuel, water, or fine solid matter that will plug the small orifices found in this system.
