Hard to say from that angle but my float (sending unit) has stops that limit the arm swing.

There are multiple posts (Search function-top right) on sending unit operation covering ground/compatibility, etc.  Yours looks similar to one posted here:

Since your gauge responds to arm movement, we can probably rule out a grounding problem.  The jump makes me think the sliding contact may be hopping off the wire wraps or a break in those wire wraps causing a break in continuity.

I recently removed mine and it looks similar to yours. I am not sure if it works or not but figured I would just buy a new one so that I know it works. They are under $30 for a new one. Of course that is just my $0.02 and I know all too well that $20 here and there adds you could always try it and see how it does and if it doesn't work replace it. Luckily that is an easy part to get to  Smiley
