AAZ Pumps - have they *ALL* got straight boost pins?

Post by Mark S »

I know there are at least 14 injection pumps for the AAZ engine. Word is that they have (mostly?) got straight boost pins such that there is effectively no extra fuelling on boost despite movement of the pin. There is a well known mod to fit a 'GTD' or Rover 2200 chamfered boost pin.

Question is: does this apply to all the pumps? Reason for question is that I am about to fit model 0460494346, which is cited as the best one according to this post: http://www.brick-yard.co.uk/forum/best- ... 33168.html.

Can anyone state for sure whether this pump already has a GTD boost pin, or is it straight like the others'?
