    Know your fuel level before it knows you. Fuel sending units and gauges give you the accurate, real-time fuel level information you need to plan your ride, your work run, or your next stop. Whether you're retrofitting a classic truck that never had a working gauge or replacing a faulty sender on a modern UTV, a quality sending unit is one of those components that pays for itself the first time it prevents a fuel-out situation.

    We carry sending units for a wide range of fuel tank applications — from aftermarket tanks with non-standard depth requirements to direct OEM replacements for trucks, ATVs, and UTVs. Many of our senders are compatible with multiple gauge types and offer adjustable float arms to accommodate different tank depths. Available in single and dual-tank configurations for applicable platforms.

    Browse our sending unit and gauge selection to find the right fit for your fuel tank.

    Frequently Asked Questions

    What is a fuel sending unit and how does it work with my aftermarket gas tank?

    A fuel sending unit is a sensor located inside the tank that uses a float and a resistor to measure fuel levels and transmit that data to your dashboard. Brands like Stewart Warner and Dakota Digital provide high-accuracy senders that interface with both OEM and aftermarket gauges to ensure you never run out of gas on the trail. Buying a sending unit that matches the Ohm range of your gauge is critical for an accurate reading.

    Which fuel gauges are compatible with custom truck and Jeep fuel systems?

    Most custom truck and Jeep builds utilize AutoMeter Ultra-Lite or Faria fuel gauges because they are designed to withstand high vibration and harsh off-road environments. These gauges are compatible with various tank depths and can be calibrated to work with heavy-duty tanks from Transfer Flow or Titan Fuel Tanks. Ensure your chosen gauge fits a standard 2-1/16 inch mounting hole for a seamless installation in your dash or pod.

    How do I choose the correct fuel level sender for a deep aftermarket tank?

    When upgrading to a high-capacity tank from Safari or Acerbis, you must choose an adjustable fuel level sender that can reach the bottom of the deeper reservoir. Many Stewart Warner senders feature a swing arm that can be cut or extended to match the specific vertical depth of your tank, ranging from 6 to 24 inches. Always measure the interior height of your empty tank before ordering to confirm the float arm has a full range of motion.

    Can I use an AutoMeter fuel gauge with a factory Jeep or truck sending unit?

    AutoMeter gauges are compatible with factory sending units as long as the Ohm resistance range matches the vehicle's original equipment specifications, such as 0-90 Ohms for many GM models or 73-10 Ohms for classic Fords and Mopars. If your factory sender is faulty, replacing it with a universal Dakota Digital fuel level sender is a reliable way to restore accuracy. If you are unsure of your vehicle's resistance range, a programmable gauge is the most versatile solution for any fuel system.

    What should I look for when buying a fuel gauge kit for a boat or UTV?

    For marine or open-cockpit UTV applications, look for a Faria fuel gauge kit that features a fog-resistant lens and a corrosion-resistant housing to protect against moisture. These kits typically include the gauge, a matching sending unit, and mounting hardware, ensuring the components are electronically synchronized for a precise read. Selecting a kit with a backlit display will also improve visibility during low-light riding or nighttime navigation.
