Abstract
Provided is an apparatus for sensing a fuel level in a fuel tank for sensing an amount of fuel remaining in the fuel tank mounted in a vehicle. The apparatus for sensing a fuel level according to the present invention senses a residual amount of fuel in a fuel tank by contacting a resistance substrate with a wiper, the apparatus including: a case that forms a sealable filling solution filling space and has a filling solution inlet formed on a top thereof; a stopper that blocks the filling solution inlet formed in the case to seal the filling solution filling space; and a filling solution that is filled in the filling solution filling space to perform an anti-rusting and lubricating function, wherein the resistance substrate and the wiper are disposed in the filling solution filling space.
