High Resolution Marine Fuel Sending Unit for Boat, Truck, and RV

The 100TECH Reed Switch Fuel Sending Unit and Fuel Gauge Kit is designed for those who are looking for a simple solution to measure the amount of fuel/gasoline level in the tank. By ordering a set that includes both the gauge and sender, users can avoid compatibility issues. With the abundance of different senders and gauges available on Amazon, it's important to understand the features and benefits of the 100TECH's offering.

Firstly, the 100TECH Fuel Sender is made with an OKI reed switch, which is imported from Japan, making it more reliable and durable. The resolution of the 100TECH 4", 5", 5.5", 6", 7", and 7.5" Boat Fuel Sending Unit is 10mm, providing a more continuous fuel level reading compared to the 21mm resolution of other senders.

Furthermore, the rod, cork gasket, and mounting screws of the 100TECH Fuel Tank Sending Unit are made from 316 stainless steel, ensuring reliable performance and a long service life. In contrast, senders made from 304 stainless steel are more prone to rust, as they have less nickel and no molybdenum.

The 100TECH Marine Fuel Tank Sending Unit can support fuel level gauges and water tank gauges for boats, trucks, RVs, and cars, operating within a temperature range of -40°F to +85°F (-40°C to +85°C). The package includes the fuel sender, fuel gauge, gasket, mounting screws, and wiring terminals, along with a sending unit installation guide.

The shorter tank requires higher sensitivity than taller tanks, and the 10mm resolution of the 100TECH Fuel Level Sending Unit provides a more continuous fuel level reading compared to the 21mm resolution of other senders. The signal output of the 100TECH sender is 240-33 ohms, with 240 ohms at empty and 33 ohms at full.

The rugged construction and long service life of the 100TECH sender are due to the use of 316 stainless steel for the body. This material offers superior corrosion resistance and durability, making it a better choice for marine applications, even though it may cost slightly more upfront.

The 100TECH Reed Switch Fuel Sender Unit is designed based on magnetic technology and made with a series of high-quality reed switches and fixed resistors. It does not require a float on an arm, dramatically reducing slosh fluctuations compared to swing-arm units. With no moving parts to break, the sender moves freely, accurately indicating the fuel level in the tank.

The 100TECH Marine Fuel Gauge is equipped with a 240° sweep, powered by stepper motor technology. The needle doesn't swing due to "sloshing" tank contents, providing a smooth sweeping motion that surpasses the original version in the boat. The gauge features an install diameter of Φ52mm or 2-1/16", an indication range of E~F, and a working voltage of 9-32V DC, suitable for 12V-24V vehicles or engines. It is also IP67 waterproof and dustproof, with a 316 stainless steel bezel.

The 100TECH Fuel Gauge offers excellent readability and visual contrast on the gauge face, with 8 selectable backlights to match the factory dashboard lights or add a custom style to the vehicle's interior. The curved lens gives a magnifying effect to the gauge face, further enhancing the readability.

Installing the 100TECH system is straightforward, with all necessary parts included, such as the NBR gasket, 316 stainless steel M5 mounting screws, and quick wiring terminals. The well-written and illustrated instructions make the installation process easy, allowing it to be completed in approximately 15 minutes.

It's important to note that the length of the sender should be 1" less than the depth of the tank to prevent it from hitting the bottom, and the diameter of the float is 1.38" (35mm), so a 1-1/2" (38mm) hole would be perfect if drilling is necessary. Additionally, the 100TECH sender has a non-linear output, so it can only be matched with a standard gauge with a non-linear signal.
