Fuel Light Thermistor

Hey guys,

Anyone know if the low Fuel Light thermistor is a replaceable item?

I've had the low fuel light permanently on for the past year and its starting to annoy me. I dont want to replace the entire fuel pump harness unless I really have to.

MV doesnt sell the thermistor or have a part number for it either, they just list the pump electrical harness which I'm assuming has a thermistor included?

This is for my 2012 F3 675.

Yes, the THERMISTOR is part of the wiring harness:

I will wager you can find a commercially available thermister somewhere....or get a scrap fuel pump from a Japanese brand bike that uses a thermister for low fuel warning (most that don't have a gauge do) and splice it in.

Or just google and find them on eBay:

The unit may not be faulty. Mine quit working a couple years ago - the single wire that is connected, broke off. A quick solder job and it worked again. (make sure it is clean and dry, residual gas makes for a flaming mess.) The unit is connected to the fuel system wire harness. Not much to it really. If it is bad buy an eBay similar unit and solder it in place. While you are in there its a good time to put in a fresh fuel filter. Regards
