The solenoid units made by Bosch for the mechanical fuel injection pumps are now over 40 years old and may have seen many thousands of service miles. Inevitably the solenoids are now starting to fail. Repair of the units is not straight forward as Bosch never envisaged the need to repair them, expecting any faulty unit simply to be replaced. Regrettably however new replacements are now no longer available from Porsche or Bosch and the supply of new old stock is all but gone. This manual leads you step by step through the repair process and is written so the repairs can be made at home by a DIY owner.

Full colour manual detailing every step of the repair process. The manual is spiral bound with laminated card front and rear covers.
