I have a 2018 33 kit with a Coyote.
Car runs great but I have never gotten the fuel gauge calibrated properly.
I have the Autometer gauges. 16-158 ohm range
It shows full when full but then goes to 1/2 tank quickly, sometimes empty, then half again, i don't know.
I even added a autometer fuel bridge to manually calibrate it and add a low fuel warning light but that didn't work either, still erratic.
I've checked my grounds, all connections soldered.
When I test it I get 142.6 ohms full and 16.7 ohms empty.
I've included a pic of a similar sending unit I found online.
Problem is I have body on and don't want to take it off, but I have not done body work yet so one option is to cut an access hole on rear deck to relace sending unit and then repair it during body work.

On a side note when I am below 1/2 tank and take a hard right turn the engine will hickup for fuel, has anyone experienced this?

Any help is appreciated! Thank you.TN1-1500-x-1500.jpg
