There is no float listed separate for the for the tank, so if there is a actual float it is a integral part of the tank, I imagine the push in sensor picks up a signal from the float in some way which seem a little complex way of doing it, as the only electrical connection/plug appears to be just to the sensor, but based on the construction and shape of the tank not sure where the float would actually be located in the tank

At the very bottom of it. You can see it pretty well in this picture.

Born and raised in So Cal. Moved to the UK in 2018 for a few years. Now in Poland and looking at moving back to the UK.

That is the push in sensor not a float.

Hi if you look closely you can see the float as mentioned it’s the light brown colour at the bottom you can see.

Ah, I see the sensor probe bit must go through the middle of it, that makes more sense how it would work, and would explain why it is integral with the tank.

Yea bloody annoying tank design on my old tank it was free to move I could hear it bouncing around when drained and off the car but it must have gone bad absorbing the water and sinking.

These manufactures slogan must be "Why make thing simple when they can be made expensive and complicated".

The advantage of this method is that there is no way the sensor can cause a leak. So clever.
Bad point is you can’t change the float.
Bmw and jaguar both use this method. Though you can usually prod the float on these

There is a magnet as part of the float.
The sensor is a reed switch to sense the magnet

Thank you all very much for your sound advice I now understand how it works thanks to you guys.
I will order a new tank and report back.
