sensitive fuel sender/gauge

[JJK]

I am using the typical 16-158 ohm mustang fuel sender, but there was not a fuel gauge that matched the ohm range for the gauges I am using. Fortunately, autometer makes a fuel bridge that converts the sender signal to match the gauge. I calibrated it and it appears to work fine. but I recently filled the tank 1/4 full while go-karting and noticed the fuel gauge moves around a lot in turns, I suspect due to fuel slosh.
Could I add a capacitor across the fuel sender wires to dampen the signal response? I was thinking something around 100 microfarad, but I am admittedly not great at counting electrons.
anyone have any thoughts or similar experience?

I have a Ford anti-slosh module installed with my Autometer gauges. It evens out the reading from the sender so the fuel gauge doesn't dance around as much.
Here is a really good thread on it, over on the other forum.

You can salvage one from a wrecking yard or spring for a new one from here: https://www.npdlink.com/product/amplifier-assy-instrument-cluster-gauge-these-units-are-designed-to-be-more-durable-than-the-oem-units-repro-e7zz-10e849-a-e9zz-10e849-a/216169

Thank you for this information, I am a bit relieved that my situation is not unique, but still frustrated that it is an issue at all. Unfortunately, the anti-slosh/voltage regulator you link is no longer available and I cannot find any online. There are some used ones on ebay, but there are different modules for different year vehicles. Looks like the one you link is for 87-90 mustangs, so I assume those are ok. Do you know if modules from any other years are also compatible. And this seems to be quite an expensive fix using 35 year old used parts. Any other folks know of an alternative solution? Is this just an issue with Autometer fuel gauges that folks live with now?

Also: I called Autometer and they had no recommendations for a solution.

That is completely normal. After a short while you get used to it and don't even notice it any more. The gauge works just fine in normal driving.

Craigs right, you'll get used to it. I switched my in-tank sender for a Mustang carburator sender, bent the arm to match the EFI sender and wired it to my Autometer gauge. Now it's accurate and doesn't do the whatusi all the time. 73-10 sender and matching Autometer gauge.

X3. It'll do it with any gauge, not just Autometers (or "35 year old used parts"). Cruising straight down the road it will be steady.

The "35 year old used parts" was in reference to the anti-slosh/voltage regulators on ebay. I would not trust any used automotive electronics that were that old to last very long. But I agree, when I am driving straight the gauge reads fine. I was just a bit alarmed to see my gauge dip from 1/4 tank to empty on a very mild turn. Sounds normal though, so be it.

Yep, and what is really funny is if your setup also has the gauge drop on hard acceleration.
