Just starting to notice that when I fuel up my gauge only goes to 3/4. I fueled tonight gauge showing 1/4 and I only put in 2 gallons. Seems to work ok other than that, no lights flashing or anything. Could this be my fuel sending unit starting to fail? 2003 1600 road star.
Yup, they're prone to fail. There's an eraser fix that works but usually doesn't last. Mine hasn't worked in years, but at less than $20 to fill up, and run to reserve then find a fueling station, it's not that inconvenient.
