[Vwdiesel] Injector pump leak 91 TD

[Bryan Belman]

That is the fuel flow adjustment screw.  They do not often leak there, but that 
certainly is easy to fix.  The hard part is getting it back to the same position 
after removing it and replacing the seal.  I would guess this seal is part of 
the full seal kit you can get from e-bay for these VE Bosch pumps.
The screw needs to be returned to the exact place.  just 1/8 turn difference 
can mean much more smoke or less.

good luck Owen.
