Warning: Before removing the fuel pump fuel module from the vehicle, read the safety instructions for working with the fuel system (see "Safety precautions for maintenance and repair of the power supply system").
Removal
1. Relieve the pressure in the fuel line in the vehicle (see "Fuel line - pressure relief").
Warning: The fuel line pressure should be relieved even if the vehicle has not been used for a long time. After the pressure is relieved, a small amount of fuel remains in the fuel line tubes.
2. Remove accumulated dust from the fuel module.
3. Apply penetrating lubricant to the studs and nuts.
4. Pressing the spring clip, disconnect the tip of the fuel line tube from the outlet (pumping) fuel module pipe of the fuel pump.
5. Similarly, disconnect the tip of the two fuel pipes from the inlet pipe of the fuel pump fuel module.
6. Using a 10 mm socket wrench, unscrew the eight nuts securing the fuel module clamping ring. There are spring washers installed under the nuts.
7. Remove the pressure ring.
8. A spacer ring and a rubber sealing gasket are installed underneath it. Replace the damaged sealing gasket.
9. Remove the fuel module from the gas tank.
Warning: When removing the fuel module, be careful not to bend the fuel gauge sensor arm. To do this, tilt the fuel pump module slightly and carefully remove the float from the fuel tank opening.
The connection between the fuel module and the gas tank is sealed with a rubber gasket.
10. Pour gasoline from the fuel module housing of the fuel pump into a container with a capacity of about 1 liter.
11. Install all removed parts on the vehicle in the reverse order of removal.
Warning: When installing the fuel pump module into the fuel tank, make sure that the lug on its cover matches the notch in the spacer ring.
The fuel line tee must be connected to the fuel module inlet pipe.
If fuel leaks, replace the sealing rings in leaky connections.
After connecting the fuel pipes and the wiring harness connectors, turn on the ignition for 5 seconds and check the tightness of the connections.
