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

 

Don't want to hijack, but since OP has same issue, where foes one find aftermarket slosh module? My searches came up empty.

 

I've seen one before but I can't remember where it was either Dakota digital or autometer. I'll do some digging if I can find anything I'll report back for you.

 

Finally used the correct search words:
Classic Instruments SN34 Fuel Link Interface - Free Shipping @ Speedway Motors

 

If I already have a gauge in the proper ohm range, is there something I can get to just stabilize it?
