Porsche Fuel metering distributor rebuild kit for 924 (1976-1985) models. This repair kit will service all Porsche 4 cylinder Aluminum Bosch fuel distributors that do not have EHA. The main reason why these units are failing is because of the introduction of ethanol into gasoline which degrades the rubber Diaphragm or membrane as its sometimes known. All of our Diaphragms are made from a material that has been scientifically engineered to resist ethanol & other fuel additives,the smallest hole or excessive stretch in the diaphragm or membrane can cause rough idle, poor acceleration difficulty in starting, or the motor just won't run. Diaphragm is included. This item will be shipped in special packaging to protect from any transportation damage.
