Fuel tank sender unit
To measure the fuel level of your vehicle, a fuel level sender is located in the fuel tank. This sender is made of buoyant material or foam, allowing it to float on the fuel. The fuel level sender is connected to a resistor with a metal rod. The resistor uses the floating sender to determine the exact fuel level and transmits this information to the engine control unit (ECU). This allows you to see how much fuel you have left in the tank on your dashboard. Additionally, the ECU can calculate how many miles you can still drive with the current fuel level. This prevents you from getting stranded with an empty tank. It is wise to replace the fuel level sender promptly if it becomes faulty.
Fuel tank sender unit fault
A faulty fuel level sender means you don't know exactly how much fuel is left in the tank. This is not only annoying, but it can also damage the fuel pump. This is because fuel flows through the pump, providing lubrication and cooling. Without fuel, the pump can overheat and become damaged. Additionally, engine damage can occur if you frequently drive with low fuel. This is because dirt can accumulate at the bottom of the tank, causing the fuel filter to become clogged. Eventually, the dirt can clog the fuel lines and injectors. It is therefore important that you replace the fuel level sender on time. You can recognise a faulty sender by the following symptoms:
The fuel gauge remains full or fluctuates between empty and full. The fuel warning light comes on unnecessarily. Replacing the fuel tank sender unit
Replacing the fuel level sender requires some technical knowledge. This is because the sender is located inside the fuel tank. As a result, the tank often needs to be (partially) removed. The exact location of the tank opening varies depending on the make and model of your car. The owner's manual for your vehicle will describe exactly where you can find this. Before you start working, you should bear in mind that you will be working near fuel. Therefore, make sure you are well prepared. Do not smoke near the vehicle and keep a fire extinguisher nearby. It is also wise to wear gloves and safety glasses while working.
