Marine Fuel Sending Units & Sensors

Knowing how much fuel is left in the tank is an important part of making sure you don’t end up stranded somewhere. Marine fuel tank sending units have a float which rises and falls on a central shaft to measure the level of fuel in your tank – giving you the information you need before leaving the dock. Fisheries Supply offers marine fuel sending units and water sensors from trusted brands like VDO Gauges, Moeller, Aqualarm, Wema-System, Xintex, Faria and more, so shop for all your boat fuel sending units today and never be stranded or out of water again!
