Understanding the Fuel Sending Unit
When I first started looking for a fuel sending unit for my boat, I realized how crucial this component is. The fuel sending unit measures the amount of fuel in the tank and sends this information to the fuel gauge on my dashboard. A malfunctioning unit can lead to inaccurate readings, which can be both frustrating and dangerous while out on the water.
