Boat Fuel Tank Sender Unit 240-33Ω 10″

Upgrade your boat’s fuel monitoring with the Sucicago Reed Switch Diesel Fuel Water Level Sensor—a direct replacement sending unit designed for superior accuracy and durability. Unlike traditional lever-type sensors, this advanced unit resists interference from waves and boat movement, providing stable, reliable fuel level readings. Your fuel gauge will stay steady even in rough waters, eliminating bouncing and inaccurate readings.

This updated version features refined sensitivity for shorter tanks, with resolution options at 10mm (4”–7”) or 21mm (8”–13”). Installation is simple with included NBR gasket, metric screws, and clear wiring instructions. Made from rugged stainless steel and backed by a 1-year warranty plus lifetime technical support, it’s compatible with diesel, gasoline, or water in boats, trucks, and campers. Note: Order a sender 1” shorter than plastic tanks or 0.5” shorter than metal tanks to prevent bottom contact.
