Bosch K-Jetronic and KE-Jetronic mechanical fuel injection systems / Fuel distributor - removal and refitting


Note: Refer to the precautions at the end of Section 1 before proceeding. It is important to note that each injection supply pipe connection in the distributor head has a screw adjacent to it. These four screws are not for adjustment and must not be removed or have their settings altered. A new O-ring and new banjo union sealing washers will be required on refitting.
