Lowrance Fuel Flow Sensor Pack – Gasoline Only For Marine Engines

Take command of your boat’s fuel management with the Lowrance Fuel Flow Sensor Pack (Gasoline Only). Designed for gasoline-powered marine engines, this compact sensor delivers real-time fuel flow data plus comprehensive usage histories, helping you optimize performance, schedule maintenance, and plan longer trips with confidence. It’s a purpose-built solution that plugs into your existing NMEA 2000 network for seamless data sharing across compatible displays and systems.

Why this sensor pack stands out

• Four valuable data outputs - Fuel Flow, Tank Fuel Used, Trip Fuel Used, and Seasonal Fuel Used. See not just how fast you’re burning fuel, but exactly how much you’re using in a tank, on a trip, and across the season.
• Multi-engine scalability - One sensor is suitable for a single engine, with the capability to support up to three engines on the same boat, giving you flexible expansion as your setup grows.
• Marine-grade integration - Specifically built for gasoline systems and designed to integrate with NMEA 2000 networks via the included N2K T, enabling reliable data sharing with compatible chartplotters and displays.
• Durable inline installation - Install above the tank’s max level, inline after the fuel filter and any Y or T fittings, ensuring stable readings without disrupting fuel flow.
• Concrete, actionable specs - 10 ft cable length for flexible mounting, 3/8" (9.5 mm) inside diameter fuel line, and a bulkhead pass-through of 22 mm (7/8 in) for clean installation through compartments.
• Reliable components included - Sensor assembly comes with a N2K T and two 1-inch hose clamps, simplifying the setup and mounting process.
• Gasoline-only assurance - Engineered to operate with gasoline fuel systems; diesel configurations are not supported, ensuring accurate readings for the intended application.

Use cases and real-world benefits

Whether you’re a weekend cruiser or a serious offshore traveler, this Lowrance fuel flow sensor pack helps you:

• Monitor real-time consumption to optimize throttle settings and engine efficiency on long trips
• Track actual fuel used against tank capacity to plan refueling stops with precision
• Identify unusual fuel usage patterns that could indicate restrictions, leaks, or injector issues
• Maintain accurate seasonal fuel data for budgeting, insurance, or maintenance planning
• Support multi-engine vessels by expanding monitoring to additional engines without sacrificing data quality

Ideal for

• Owners of gasoline-powered boats with one to three engines seeking precise fuel usage data
• Boat owners integrating fuel monitoring into an existing NMEA 2000 network for unified data on compatible displays
• Marinas or fleets that require reliable, scalable fuel analytics for maintenance planning and trip budgeting

Why choose Lowrance for fuel management

Lowrance brings decades of marine electronics expertise to fuel management with hardware designed for the rugged realities of the water. This sensor pack extends the brand’s reputation for dependable, plug-and-play solutions that work in harmony with common marine displays and networks, helping you turn data into actionable decisions on every voyage.

Technical notes and practical tips

To maximize accuracy and reliability, install the sensor per the specified location and use the included N2K T for network access. The 10-foot cable provides flexible mounting options, while the 3/8" ID fuel line aligns with standard marine fuel hoses. If you’re expanding to a second or third engine, plan sensor placement to minimize hose length variation and ensure clean routing through the bulkhead.
