Are  there any other
locations that might let air in without leaking diesel fuel  out when
running?  Any other thoughts?




Lots and my Rabbit had all of them at one time!
  The fuel return hose gets weepy with old age (the bigger, to the 
tank one).  The small lines can leak, especially at the injector 
nipples, if it's vacuum hose instead of the yellow stripe stuff. 
Injector nipples can get bumped and crack or simply leak where 
pressed in.  Banjo bolts can leak a little if not tight, dirt,  etc.
ANY hose to tube fitting can loosen up over time as the hose ages.
Don't forget return line to tank fittings if all else failis.
  Leaks will generally leak air before they leak any fuel but USUALLY 
will be slightly dampened at least.  Clean any suspect areas with some 
aerosol brake cleaner then run a bit.
