• Peugeot 106 (1991 - 2002) - 1995 1.5 diesel - air in fuel system 15 Apr 2008 (Forum)
  I can push the pin into the plastic body against a spring pressure and by gripping the pin with a pair of pliers it can be completely withdrawn from the housing. The pin is about 1" long and 1/16 in diameter. When I operate the fuel priming pump diesel fuel is emitted from the join between the housing and the pin; so presumably air can also be drawn in here. What is this 'valve'? and can anyone venture an opinion as to what could have caused it to fail?
• Ford Mondeo 2.0 Diesel 2005 55000 miles - Glow Plug Light Flashing/Engine Cutting out 27 Oct 2015 (Forum)
  It may also go into limp home mode and the engine management light will come on. The issue will be in most cases the Diesel Injector Fuel Pump - cost to replace - about £1100! Don't listen to anyone about water in the fuel, camshaft sensors, crankshaft sensors, even injectors. These are all red herrings. There is a known problem with the internal workings of the fuel pump that fail and send swarf through the system.

• Dead Fuel Injection Pump? 17 Nov 2003 (Forum)
  I?m sure this?ll be an easy one for the experienced guys out there! I had cause to disconnect my fuel tank on my Peugeot 309 GLD 1.9 diesel (1988), creating an almighty air lock in the feeder pipe to the fuel injection pump. I reconnected the tank but the engine sort of half spluttered but never actually fired.
