A small profile fuel level sensor has a small float located in a vertically-oriented housing in a fuel tank, and instead of sliding against two resistive strips that output a level signal as fuel level changes, the float is drawn to and rolls against the two strips owing to the presence of a magnetic strip on the side of the resistive strips that is opposite the float. Accordingly, with the magnetic strip attracting the float against the resistive strips to force rollable contact therebetween instead of slidable contact, much less friction must be overcome to move the float and, hence, use of a relatively small float and overall small sensor assembly is facilitated.
