Fuel Probes - Vertical Positioning

An earlier poster mentioned that the fuel probes (presumably capacitance type), for crashworthiness reasons, do not go all the way to the bottom of the tank.

If it is possible that one or more of the probes could had been fitted lower than intended, this would have given a greater fuel reading than is actually present, and a false sense of security. Can anyone shed any light on the type of fuel probes and their mountings to say if this could be possible?

There has also been mention of a red light giving incorrect fuel level indications. From where does this get its information, the fuel probes or an independent sensor?

Note: My own limited experience with capacitance probes was characterizing those for Typhoon & Nimrod MRA. 4. Characterizing means recording the capacitance value for a given depth of immersion in fuel. I have no helicopter gauging experience.
