2 little holes

Post by paul-jackson » Mon Nov 24, 2014 8:00 pm

hello , thank you in advance, 1190. Had a wiff of warm diesel for some time (,occasional,) I have now found where its coming from. On the spill/return pipe from the injectors the line goes to a very small cylinder ( about 2 inch deep, at the rear of the engine)looks like a fuel reservoir for the thermo start, From this cylinder there is one thin fuel pipe that does go to cold start ,the other pipe returns to the fuel tank, in this return pipe , at the connection with the small cylinder (metal connection) there is two very tiny holes, these weep fuel and it runs down the pipe. WHY, any ideas please. (the return pipe is not blocked)

If I am not mistaken (which I may be), that "cylinder" is a gauze filter?

The cold start gets its fuel supply from the leak off pipe from the injectors.

Hi, are they actually drilled holes or rust holes ?

If rust holes then mystery solved. I have never noticed holes there, in which case the easiest thing may be to replace the leaking connector.

The cold start gets it's supply from the small plastic 'barrel' reservoir. As I said I think they may be breather holes to allow air into the reservoir, in which case they need to remain unblocked.
