This is very intersting to me too.
My guage is reasonably accurate, but when it gets to zero the pump just stops. It doesnt seem to spit air, just stop and the taps gently run dry. I took the hatch off and looked inside and would estimate that there was about 2 inches of water in the bottom. I found it was possible to force the pump to run by holding down the pump button on the panel whilst turning the tap on. I dont know if running the pump dry will damage it or not but it is mighty annoying to have water in the tank and to not be able to get it.
On another note i plan to mod the overflow by fitting a flexible pipe to it and then bringing it to the side of the van and sealing with a pipe clamp. I can then open and seal off the overflow as needed as i think it sloshes out on the road. My blue overflow pipe also moves about 10mm up and down so i guess in the down position it will overflow sooner.
It may be of interest that all the sensors, take off pipe, overflow, heater and fill pipe are at the front of the tank so if you are running out of water then parking nose down a hill will allow you to get some more water out of the tank and also best not to fill it when nose down a hill as it wont get full.
