My 2000  golf with ~258k miles on it has what I think is an IP seal 
problem.   It started having a mist of oil/diesel on it a few months ago. 
Then it  started needing more cranking time as there were bubbles in the 
clear fuel  line after sitting. Now the IP has lost prime and won't pull 
fuel (even  with a mighty vac on the return line).

It seems to me that these  symptoms point to the main oring between the 
aluminum IP body and the iron  IP "distributor".  I am thinking this 
because of the increased air  leaking into the fuel system and the lack 
of being able to prime the pump  now even when pulling a vac on the 
return line. But it's just a guess on  my part, based upon reading others 
descriptions.

Any thoughts on  this?  Is it likely this seal gone bad, or is something 
else going on  here?




More often those symptoms are from a leaking fuel line (more often  the 
return than the supply)  or a leak at the input shaft seal rather than  the 
distributor o-ring.
  Not priming up, even with the mitee-vac sounds like a really bad air  
leak or 
a stoppage somewhere.  Dirty fuel filter?  Often the fittings on  the 
fancy, preheating 
fuel filters will leak enough air to keep the car from running well or at  
all.  
BTDT on Dad's Passat TDI.  I've been lucky so far.
