How Does an Electric Fuel Pump for Dual Tanks Operate?
An electric fuel pump for dual tanks operates by transferring fuel from both tanks to the engine. The system includes a fuel pump, a switch, and fuel lines.
First, the driver selects which tank to draw fuel from using a switch. This switch activates the appropriate pump. Each tank has its own electric fuel pump designed to pressurize and move fuel.
Next, the fuel pump draws fuel from the selected tank. It creates a vacuum that pulls the fuel through the fuel lines. The pump then pressurizes the fuel and sends it to the engine.
The fuel flows through a filter to remove impurities before it reaches the engine. This process ensures that the engine receives clean fuel for efficient combustion.
Finally, the fuel pump continues to operate while the vehicle runs, maintaining the necessary pressure to support engine performance. If one tank is empty, the driver can switch to the second tank, allowing the fuel system to function seamlessly.
