    Default Anti Slosh Module?

    Does anyone know where the anti slosh module is on our cars? On Fox Stangs, it's on the back of the instrument cluster. I checked a spare T Bird cluster I have and don't see one.

    Hey Mike,

    Don't feel bad. A lot of guys don't know what an anti slosh module is. When you're going down the road and hit the brakes, or accelerate hard, the fuel in your tank obviously sloshes around. To prevent your gas gauge from fluctuating when the fuel sloshes, Engineers designed a device for your car that's called an anti slosh module. This module takes the average fuel level over a wide period of time and uses that information to determine what your real fuel level is. When this module goes bad, your gauge will start to fluctuate and reflect your fuel's sloshing action, or your gauge will read empty all the time.

    When fuel gauges in out cars read incorrectly, it's most commonly a bad sender. Your anti slosh module is the 2nd most likely culprit.

    The baffle helps, but not enough by itself. A lot of tanks have baffles AND anti slosh modules though.

    the integrated 5v voltage regulator wouild act as that and supervise slosh.

    the needles delay very strong to quick changes due to the design.

    never heard of it on our cars.

    never ran across it in the shop manuals either.

    like more info on this ,, no one has ever mentioned this module before and so it seems reasonable that there is room for pause on our parts.

    I would think that the heated bi-metallic strip design of the small gauges in these cars would act as a de-facto anti-slosh module. Because the needle moves by heating a coil wrapped around a bi-metallic strip the needle is slow to react...

    I must say I have never heard of these before. I wonder if my 77 F150 has one, because when I floor it the gas gauge drops pretty fast then bounces back up when I let off.
