does the little pin on the diaphragm go towords the pump or towords the engine block?

towards the block i think, then you turn it clockwise to increase the on boost fuelling.

I think we might need a clearer picture of what you are talking about.

Jim is referring to the shaft attached to the diaphragm on a Bosch VE pump. It has an eccentric cone on the end that control the fueling rate as boost increases. Depending on which angle this is set at, the fueling rate varies.

Do you mean this bit:

you can see that "normally" the dot is at the top, closest to the engine block.

it's turned around to between 3 o'clock and 6 o'clock for extra oomph.
