From what I know about CIS it does not have anything, not like a carb where when you move the pedal it squirts fuel. Carbs rely on vacuum to bring fuel in from the float bowl where CIS has fuel pressure and reacts to how much air is moving past the air flow sensor plate.

I should say not all carburetors use accelerator pumps SU carbs and most motorcycle similar to SU don't.
