Speedway Tech Talk - Attach Stock Fuel Sender to any Gauge
The Speedway Motors Fuel Gauge Interface Module is wired inline between the sending unit and fuel level gauge. Before powering the unit, remove the back cover of the module and select the appropriate sequence of limiters that correspond to the necessary ohm rating your gauge set needs.
Pat does draw attention to the fact that this module maxes out at 240 ohms. Some vehicles use a sending unit that functions close to 500 ohm, so make sure to keep that in mind.
A useful feature that was built into the Fuel Gauge Interface Module is the potentiometer. Once wired in, you may notice that the fuel gauge needle isn’t reading correctly on empty or full. You can use the included small screwdriver in the kit to adjust the Fuel Gauge Interface Module to have that needle read where it is supposed to.
