Marine Fuel Sending Unit, 9-Inch Fuel Level Sensor, Stainless Steel Boat Fuel Sender Float Unit

The Marine Fuel Gauge and Sending Unit Kit comes with detailed instructions for proper connection and installation. The kit includes a stainless steel fuel sending unit, a gasket, and five M5*16 screws.

The connection process is straightforward: the blue wire should be connected to the ground (-), and the brown wire should be connected to the instrument signal wire. If your gauge has color-coded hookups, be sure to maintain this coding when connecting the sender and ground wires.

In terms of specification, the fuel sending unit is made of high-quality stainless steel, providing a durable and rust-resistant solution. The protection rank is IP67, ensuring reliable performance in various marine environments. The mounting method follows the standard SAE 5-hole pattern.

The output signal range is 240-33 ohms, with a resolution range of 21 mm. The length of the fuel sending unit can be customized, with options ranging from 4 inches to 15 inches. For lengths beyond this range, customers are encouraged to contact the manufacturer directly for more information.

It is important to note that when the oil or water level is empty, there will be a 3-15 mm space between the sensor float and the bottom of the sensor. This is a safe distance, and the fuel sender marine can still function normally.

The fuel level sensor is suitable for a wide range of applications, including trucks, generators/gen sets, buses, and marine vessels. It can be used with various liquids, such as fuel, water, kerosene, and chemicals, as long as they are free from impurities.

The installation process is straightforward and user-friendly. The marine fuel sending unit is of high quality, with a simple and sturdy structure that is resistant to vibration and explosion. The damping cover is optional and can be easily assembled with a C-ring, facilitating the installation process.

For the hole size, a 36 mm hole saw is recommended. The float diameter is 1.370" (34.8 mm), and the gasket ID is 1.44" (36.48 mm), providing sufficient clearance for the installation. To ensure proper alignment, the little bump/tab on the gasket should be positioned beneath the cord on the sender, making it easier to align the offset holes regardless of the sender head orientation.

Overall, the Marine Fuel Gauge and Sending Unit Kit offers a reliable and versatile solution for monitoring fuel levels in various marine applications, with a focus on ease of installation and long-lasting performance.
