Kugelfischer pumps (model 71 i.e. 72tii's) and the later ones found on 74tii's?

Is there a visible difference or are the changes to A4 internal?

Never had 2 side by side to compare....

internal fuel cone. It is set up to run leaner at low throttle and richer at high throttle then the earlier b3 (i think that is the designation?) pump

Visibly, to me the first thing I notice is the difference between the mechanism that runs the warm up regulators. The lift linkage was simpler on the later models.

I think the majority is internal to the cone inside the pump, Mars.
