The lift pump is regulated to 1.25bar within the fuel filter housing.
The ECU has no clue over the low pressure circuit, however if the low pressure circuit starts starving/dropping pressure, the HP pump will be starved also, which means it'll fail to make pressure. As stock there is a maximum ±250bar deviation allowed before a fault code is set.
