[Vwdiesel] '93 EV diesel injection pump leaking

not sure what exactly is leaking


  That's the first step, clean, rinse, blow it off and find out exactly 
what is leaking.  Probably a return hose but not necessarily.

  Depends on what's leaking.  Seals and o-rings can be replaced.  
You generally have to remove the pump to get at them.

  Again, depends on what's leaking.  If it's the front seal, which usually 
leaks air in rather than fuel out the bushing is usually worn and needs 
shop repair.  A seal kit is available for about $25 and you can replace 
what's leaking.  Timing advance lever isn't bad but the one between the 
cast iron and aluminum part is a bit nasty as I understand.  Fuel out 
the throttle shaft would need a new bushing.  Might be available as a 
press in part.

  Sounds like a small hose leak really.  Maybe at the injectors instead 
of the pump?
