Pessimistic Fuel Gauge

Does it work when car is switched off?

The water separator under the fuel filter separates the heavier water from the fuel flow.

It starts working as soon as you start the engine, and the low pressure/high volume pump starts forwarding fuel from the tank to the high pressure pump near the engine.

(High volume, like a couple of liters per minute)

Any fuel that is not used by the injection system flows back into the tank.

So, the entire content of the tank passes the water separator and fuel filter many times as long as the engine is running.

In other words, the lower the fuel level, the cleaner it gets. :)

Fuel tanks are designed such, that heavy particles are kept in an area where they cannot easily get to the fuel pump.

Easiest way to see how low your fuel tank can go is to lend your car to your son.
