The Lowrance Fuel Flow Sensor is designed for use with gasoline engines and features a 10-foot cable and T-connector. It is a vital component, with one required per engine, and can support up to three engines simultaneously. This sensor provides several useful outputs, including fuel flow, tank fuel used, trip fuel used, and seasonal fuel used.
The sensor has a cable length of 10 feet and is suitable for use with fuel lines that have a 3/8″ (9.5mm) inside diameter. It is optimized to measure flow rates between 0.6-45 gallons per hour, though it can still provide accurate measurements outside of this range.
When installed, the sensor adds a back pressure of 0.5 PSI at 20 gallons per hour and 1 PSI at 40 gallons per hour to the fuel system. It should be positioned above the maximum level of the fuel tank, in-line after the fuel filter, and any Y's or T's in the line.
The package includes the Fuel Flow Sensor, an N2K T-connector, and two 1″ hose clamps. It is important to note that this sensor is only compatible with gasoline fuel systems and cannot be used with diesel engines.
A 22mm (7/8″) hole is required to route the sensor through a bulkhead, and it is possible to use multiple Fuel Flow sensors if needed.
