Gas Gauge Question

Hi all, I've rewired from my original gas gauge to an aftermarket Equus gauge. It seems to be accurate to around 1/2 to 1/4 tank. Anyone know if this is normal or is it related to the quality of the gauge? Should I look into replacing it with an Autometer gauge? Thanks

My Equus gas gauge works all the way to empty, so I would say it's accurate. However, my issue is how much it bounces around while I'm driving.

I have the bouncing issue too. I wonder if there is any way to stabilize it? I'm also not entirely sure how large my tank is. I haven't ran it empty yet, and I don't exactly know how accurate the gas gauge is.

You'd need to find an aftermarket slosh module or try to adapt a factory one from a newer (90s) Ford to stop the bounce. The original didn't bounce due to its design, it took a little time to heat or cool the bimetallic strip that moves the needle, that averages the sloshing. To test the gauges empty point, I usually put a five gallon can of gas in the bed and drive til it dies with the new gauge, keeping track of the miles after empty till it dies, then I dump 5 gallons in it and head to the gas station, LOL
