I have noticed recently a diesel smell. Checked the two known places, rear green fuel line and pressure regulator.
No sign of leak. My son borrowed the car yesterday and came back saying that it has a bad leak.
Well what an understatement. The fuel hose that runs from pressure regulator along the inlet manifold and into the head.
Where it screws into the head at the front the nut had come loose and while my son had it the nut had completely come undone.
Today's job was getting it back in and tight.
