Primary Fuel Tank Fuel Pump Module

The electric 3 phase style fuel pump attaches to the fuel tank fuel pump module inside the left fuel tank and supplies fuel through the fuel feed pipe to the high pressure fuel pump. The fuel tank fuel pump module contains a reverse flow check valve. The check valve maintains fuel pressure in the fuel feed pipe in order to prevent long cranking times.

The fuel tank fuel pump module is located inside of the fuel tank. The fuel tank fuel pump module consists of the following major components:

• The ultrasonic level sensor
• The fuel pump and reservoir assembly
• The pressure relief regulator valve
• The fuel strainer
• The primary jet pump
• The secondary jet pump
