Looking to isolate the source of a nagging leak from the bleeder line on the D6-9U. This is the line that runs down the side of the fuel filter 'tower'. My late serial unit has an additional line that joins into the line that starts at the top 'knob' bleeder on the filter housing. Anyway, I have determined that it is not originating from the top bleeder valve.
Can anyone tell me what the exact source would be for the other line that joins the one from the top of the housing; and what the particular problem might be for fuel escaping past that source?
The 'leak' is substantial enough to prevent operating the unit for any more than a minute or so, (especially with these diesel prices ). More than a drip and not quite a steady stream. I have recently cleaned the housing out and 'rebuilt' the fuel transfer pump. Also replaced the seals between the injector pump and f.f. housing.
Hope someone has run into this problem before and can direct me to a solution! thanks
