Universal fuel gauge for 8-18 V systems

This 52 mm digital gauge displays fuel level from empty to half to full using a resistance-type sender. It is designed for automotive applications where a compact, direct-read instrument is required. The unit operates on 8-18 V supply and includes the gauge, sender and wiring harness. Installers needing a simple, calibrated fuel readout will find it suitable.

Thermals noise and power draw

The gauge draws minimal current from the vehicle electrical system while the ignition is on. No fan or active cooling is present so operation is silent. Heat output is negligible and does not affect surrounding trim or wiring. Normal use imposes no measurable load on the charging system.

Calibration routine and bundled sender

The included fuel-level transmitter matches the 2 K resistance range expected by the gauge. A three-second button press starts a two-point calibration: set the float at empty, press once, then at full, press again. The LED array then scans once and enters normal display mode. The supplied power cable and sensor complete the installation without extra parts.

Questions about this item

How do I wire the red, green and black leads during installation?

Connect the red wire to the ignition ACC, the green wire to the fuel sensor signal, and the black wire to battery negative; the step often missed is holding the button for three seconds to enter calibration mode before setting empty and full.

What part will need replacement if the reading drifts over time?

The resistance-type fuel level transmitter with a 2K measuring range is the wear item; the gauge itself has no user-serviceable components.

At what voltage will the display stop working during a long drive?

The unit operates from 8 to 18 volts, so a sustained drop below 8 V will cause the gauge to shut off first.
