More accurate Fuel Sender for Mobius?
Is a more accurate Fuel Sender available for the Mobius?
The gauge fluxuates by 1/4 tank the whole time we're riding, and the gauge is reading at least a 1/4 tank lower than it actually is at all times. So the gauge reads between 1/4 and 1/2 tank lower than it actually is at all times (except the first 15 minutes of riding when it reads Full).
I read where a lot of drivers just estimate based on how far off it is, but I imagine there should be a more accurate sender than this.

It's a float sensor so the fundamental problem is that the fuel is moving around due to the boat's roll and pitch; a more accurate sensor doesn't change that. Mine moves as much as a 1/4 when in an aggressive nose-up attitude/pitch like surfing. I think you just get used to it and only take an "accurate" reading when sitting flat, still and calm. Possible solutions would be to measure the tank in multiple locations or to measure roll/pitch and then calculate fuel volume but that is much more complicated than a single float sensor and a disclaimer that it's only accurate when the boat is level.

My LSV seems to register about 1/4-1/8 below what i actually have but i've just learned to deal with it. No biggie for me. My 2017 Tundra does the exact same thing. The gas warning light will come on and i will drive it until the computer says 0 miles till empty and i can only put in 30 gallons and it holds 38 gallons. Go figure.

Mine is both top heavy and bottom heavy. When it's full it doesn't bounce. 3/4 down to 1/4ish it tends to bounce. Then from 1/4 down it's pretty stable again. I think I have a 40 gal tank but I've never been daring enough to run it that low. I'm pretty sure the most I've ever put in is 32 gal.
And 38 gallons in a Tundra? Chit man, that's more than my long bed gas guzzling v-10 F350 used to hold...So when is this "old enough to know better" supposed to kick in?
