Odd, the needle on my fuel gauge "ticks" (moves back and forth slightly, a millimeter or so) in time with my turn signals, when the turn signals are on. Anyone seen that before or know why? I assume some sort of grounding issue.
What year car?
'73 1.7
I can probably make a video if it's not clear what I mean.

The ground isn't staying a ground, or the power to the gauge isn't staying at full voltage.

My tach needle does the same ???? 
Clean all the grounds under the dash to the ground stub on the chassis.
Located under the fuse box to the side. Clean each wire individually.

Fuse #8 (I think?) being popped can cause similar symptoms, if your tach is jumping around. Check, remove, and clean all fuses and the fuse holders.
