    Default 405 Diesel Query

    Can someone tell me please where the two overfuel lines go from the two end injectors (cylinders 4 &1) it appears number 4 line goes to the fuel return line coming off the pump but where does no 1 cylinder (flywheel end) line connect up to?
    Car is `92 1.8 turbo model with the Lucas/CAV pump.-bought car with engine partially disassembled requiring head gasket. Haynes manual does not give fuel flow diagram and no obvious connection point.

    It usually has a blanking cap on it.

    Yes. One goes to fuel return line, while the other has a blanking cap. You can get these from any good diesel specialist for a couple dollars.
    May i suggest you replace all fuel overflow lines coming from the injectors as the old ones, once disturbed, have a tendency to leak. Again, easiest source for these is your nearest diesel specialist.

    Good luck with the re-assembly of the head.

    not only do they leak but if you can get them back on again it would be a miracle as they tend to go rock bloody hard

    new ones or a length of line is cheap so well worth the effort

    Thanks chaps, I was begiining to wonder about whether it had a blanking plug.
    You are so right regarding the line going hard but already bought the new fuel hose-something I`ve learnt from the past.
    Many thanks to all that answered. Just off to buy a new battery as the tip to use epsom salts to restore a sulfated battery hasn`t worked in my case-there goes another $200-$250.
