K-Jet 8v and 16v pumps are the same and match the pressure of the 16v ABF pump IIRC

Digi 8v pump is weaker than the K-Jet 8/16v pump

AFAIK you can't run an ABF off a standard Digi 8v pump - it doesn't have enough flow ... RJ/DP/DH/DPB will correct me I'm sure ;)

MK2 digi pump will run an ABF fine :)

MK3 GTI 8v/16v pump is rated for 3bar, not sure about the digi but I'm pretty sure its also 3bar.  if i can get the bosch number off one I can find out.

edit: digi mk2 pump specs:
0 580 453 914 - 3bar - 75 L/HR

edit2: actually I just remembered the early SEAT Toledo ABF used the same pump as the MK2 digi, so it definitly will work :)

and your point is what? original question was already answered, i was just clarifying that the abf will work on a digi pump.
