Why does the SuperStore fix kit have that big box when this kit has just the 2 wires? Do they both work the same way?
My kit is a trimpot resistor that dials in the fuel sender to be calibrated the way it was from the factory. You see, from the factory the fuel gauge sender is 90 ohms when full. Over time the sender “weakens” and reads 120-150 ohms when full. So by installing my calibrator kit in parallel with your fuel gauge sender, you are able to bring that resistance back down to the 90 ohms it’s supposed to be. My kit is considered a “passive” kit since it is a one shot deal and only specifically calibrates the full end of the gauge. Typically the low end behaves like it’s supposed to once my kit is installed. Now the SuperStore kit is an “active” calibrator and is theoretically capable of adjusting the low end also. In theory the SuperStore calibrator “actively” adjusts itself to correct the fuel gauge throughout the entire range, that’s why it needs a power connection and that’s why it has two trim dials on it. My point here is that both kits essentially accomplish the same end result, but my k
