Re how long does 4kg last

If both supply tanks had the same amount of fuel at a given reference time and both engines have a similar rate of fuel burn and useable fuel is the same as fuel remaining for both tanks, then both engines will flame out at approximately the same time. It is the useable fuel in both supply tanks at a certain reference point in time that matters, not the relative fuel tank sizes.

It is the left supply tank low fuel warning that will illuminate approx 2mins 25 seconds before the corresponding right hand one at 32kg and 28kg respectively, if they are working correctly, not one engine flaming out 2' 25 before the other.

What is niggling me is the multiple intermittent low fuel warnings issued by the left hand tank sensor. That doesn't seem normal behaviour to me. The right hand one illuminated later and illuminated permanently. Why were the two behaving differently?
