To answer your question when the inertia switch operates the negative supply to the tank pump is disconnected.

I am no expert but am certain as the low pressure pump in the tank is electric whilst the high pressure pump at the engine is mechanical e.g it is driven by the timing belt on the Fiat Ducato 2.3.
