Does it flow that much more? I found this very helpful:

FWIW the pump stroke on the N20 is around 4.6mm. I assume I measured it wrong, and is really 4.7mm, in which case it matches the N55 exactly. If true that means the N20 fuel system can flow as much fuel per revolution as the N55, even though it only has 2/3 the number of injectors (meaning each N20 injector can inject 1.5x as much fuel as an N55 injector).
