I’m having an issue where my fuel gauge drops down quite a bit while I’m driving normally, I literally just pumped a full tank yesterday and I’m down to a half tank today lol I have an aem wideband too and my afr’s are good they’re in the 13’s. And every once in a while the gauge will go up higher than where it was currently at and shortly after it drops down to where it was previously at. Any help is appreciated

 

Civic fuel gauges are fine. In contrast, Civic fuel sending units suck.

 

So it most likely is my fuel sending unit?
