    I was only able to see some inside layers a toyota townace fuel tank. and I believe sa bandang ilalim nga. peru hindi sa "pinaka" lalim. because when we emptied it, cleaned it and put it back with 6 liters. when we start it, the ride gives prelude to air lock signs with the 6 liters, even revving it long, on a straight surface. so we top it with additional 5 liter and then it runs fine.

    so this particular ride will never run out dry. it will stall the engine with atleast a few liters still left inside the tank.

    for other rides I don't know though...

    Yes, it doesn't move but the sediments are heavier than the fluid they are suspended in so they remain at the bottom of the tank as long as there is a healthy amount of fuel in it. However, as the fuel/fluid goes down, then the system will start sucking dirt that were originally associated with the fuel at the bottom of the tank.

    This is the reason I stall the Benz when I drive it below one fourth. After cleaning the filter and refuelling, I'm OK again.

    and if some particles and/or few ml/drops of water happen to float, natural pwede masipsip ito mas mabuti pa ring sa gitna sumipsip/kumuha ng fuel kesa sa ibabaw. yan ang bentahe ng maraming laman.

    I've been doing this for several years na rin. I could run as far as 120km more before re-fueling again.

    The concerns here are residual dirts from the bottom of the tank getting sucked and passed your fuel filter then clogging your injectors. You know what will happen next when the clog really builds-up afterwards.

    Well, as long as you religiously follow your fuel filter periodic change and having fuel-up on a reliable station, there is less to worry.

    Clogged-up injectors occur very rarely if not remotely.

    The principle of preventing rust build up in the fuel tank somewhat relates to the amount of fuel inside it. The more fuel you have, the less space there is for moisture to stay in. So if you constantly run with low fuel, then you've got a lot of dead airspace inside the tank, and we all know it's very humid back there.

    Humidity inside the fuel tank causes rust, which causes more debris to form. This is also the same reason why, when storing a car for a long time, owners fill the tank to minimize the moisture inside.

    Yeah.. just follow the rule of thumb regarding refueling:

    -refuel when the indicator is around 1/4 already.
    -put in fuel that fills at least 3/4 of the tank.

    Then you will 100% ok. Of course, be careful where you filled up.
