case dozer cummins 4bt question

My 2005 Case 750K with the Cummins engine has a fuel leak. I cant tell if its from the high pressure line or the return line. Can anyone point me toward a part number for the line in the picture? Thanks

    Clean the fittings off and see which one is leaking may just be loose. Bob

    Or a bad copper washer in the bango fitting.

    Seepage or weeping, collecting and washing off dust will be really hard to pinpoint but there are washers on both the large and small bajo fittings, most likely as noted just loose.

    Where do you see a large banjo fitting? Bob

    My OOOPS, meant the HP line to the nozzle MIGHT be loose slightly can happen, the banjo at the return side is obvious!!

    1st thing you NEED TO DO is pressure wash that engine.. Theres a copper "horseshoe" gasket on that small line w/ the screw.. IT WILL break if you over-tighten it.. The new ones don't have holes in them.. just a "flat" ground into the threads.. easily made "in shop"..
