Fuel level sensor 280tri

[larro]

As above. Has any body removed or knows how this sensor is attached. I think mine is very lightly weeping and don't want to damage anything to sort this out. Thank you.

Thank you konrad much appreciated.

Following on from this i have tried to undo this sensor but there seems to be to much flex in the 14mm head so much i think it will just twist off leaving the rest in the threaded hole. If this happens i  do not think i will get a new part. Any suggestions if it breaks. Thank you.

Found this on ossa-efi re the fuel level sensor:

"The sensor is used to illuminate an optional warning light when less than 3/4 liter of fuel remains."

"The complete circuit is just the thermistor, an incandescent light bulb, and 12-volt power all connected in series. "

If that is true all the fuel level sensor does is turn on a warning light.

Thanks Lemur but i know this information. My post as above was asking if this unit breaks is there an alterative unit available. Thanks.

Does your bike even have the low fuel light?  Most did not.

Just plug the hole by threading in a bolt.  One of my early mods was to make a fuel level sight tube, but I ended up not liking it: Photos here: https://www.ossa-efi.com/home/my-upgrades/minor-modifications

Hi konrad. No light but was going to make something work. I have already thought about using some sort of plug but wanted to try and use the sensor but i have a feeling that it is just goint to snap the head. My concern is what will break off and fall into the tank as that is another job i don't want to come across that does not need to happen. I have a feeling that the fuel might even be seeping through the internals of the sensor but i dont know for sure as it seems to be damp around all of the area. Argh

Well as usual my bad luck has risen yet again the head of this sensor has snapped off leaving the rest of the sensor in the thread. The unit is well tight in the thread i think that a thread lock material may of been used and with the unit being plastic it was just too tight for the head not to break. The o-ring seems ok so why it was weeping i don't really know. I have mentioned before that maybe it was coming through the unit itself as where the electric connector would fit in was always damp with fuel. Anyway i have a bigger job now and am a bit stuck as which way to go. Just couldn't unscrew could it oh no.  Thanks.
