100TECH Fuel Gauge Sending Unit for Marine and RV Applications

The 100TECH Fuel Gauge Sending Unit is a high-resolution solution designed specifically for marine and RV applications. With a length of 5in (130mm), this unit is crafted from 316 Stainless Steel, ensuring exceptional durability and corrosion resistance. Unlike traditional sending units, this model offers a finer resolution of 10mm, making it ideal for short tanks that require higher sensitivity. The signal output ranges from 240 ohms when empty to 33 ohms when full, providing accurate readings for your fuel level.

One of the standout features of the 100TECH Marine Fuel Tank Sending Unit is its rugged construction. The use of 316 Stainless Steel not only enhances its longevity but also means you won't have to replace your sender frequently, saving you money in the long run. This material is superior to 304 stainless steel, which rusts faster due to its lower nickel content.

Designed with magnetic technology, the 100TECH Reed Switch Fuel Sender Unit eliminates the need for a float on an arm, resulting in smoother readings even in rough waters. This innovative design dramatically reduces slosh fluctuations compared to swing-arm units, ensuring that you get accurate fuel level indications without the worry of moving parts breaking.

The 100TECH Marine Fuel Gauge features smooth sweeping capabilities powered by stepper motor technology. This means that the needle does not swing due to sloshing tank contents, providing a consistent and reliable reading. With an installation diameter of 2-1/16in (52mm) and an indication range from empty to full, this gauge is compatible with both 12V and 24V vehicles or engines.

Another impressive aspect of the 100TECH Fuel Gauge is its easy readability. The gauge is equipped with 8 selectable backlight colors, including red, green, blue, and more, allowing you to customize the look to match your factory dashboard lights. The curved lens provides a magnifying effect, enhancing visibility during both day and night.

Installation is a breeze with the 100TECH Fuel Gauge Sending Unit. It comes with all necessary parts, including a gasket, mounting screws, and quick wiring terminals. The well-written instructions make the installation process straightforward, allowing you to complete the setup in just 15 minutes.

Before installation, it's important to note that the length of the sender should be 1in less than the depth of the tank to prevent it from hitting the bottom. The float diameter is 1.38in (35mm), and if drilling is necessary, a 1-1/2in (38mm) hole is recommended. This unit is designed to work with standard gauges that utilize a non-linear signal, ensuring compatibility with your existing setup.
