Withdrawal
1. Relieve fuel pressure (see section 2).
2. Disconnect the wire from the negative battery terminal.
3. Remove the fuel tank (see section 6).
4. The fuel pump and sensor are inside the tank. The pump is fastened with a ring clamp, which consists of an inner ring with three locking locks and an outer ring with three locking shanks.
5. To disengage the fuel pump and sensor, turn the inner ring counterclockwise until the retaining tabs are free from the shanks (see illustration).
7.5. To remove the fuel gauge and fuel pump (1), turn the inner circlip (2) counterclockwise and remove the pump and O-ring from the fuel tank. Be especially careful not to damage the float mechanism
Note. If the rings are too tight together and cannot be released by hand, lightly tap a brass punch or wooden pin with a hammer.
Attention! Do not use a steel punch. A spark during operation can lead to an explosion of gasoline vapors.
6. Remove the fuel pump and sensor from the tank (see illustration).
7.6. Remove the fuel pump from the fuel tank
Attention! The float and sensor are sensitive devices, do not hit them against the retaining rings during removal, otherwise the sensor may be damaged.
7. Replace the o-ring around the ring clamp inlet.
8. Check the filter at the lower end of the fuel pump (see illustration) If it is dirty, remove it, clean it in solvent and blow it out with compressed air. If the filter is too dirty and cannot be cleaned, replace it.
7.8. Fuel pump and sensor details: 1 - sensor, 2 - pulsator (only on 3.8L engine), 3 - damper, 4 - fuel pump, 5 - sound insulating sleeve, 6 - sound insulator, 7 - filter
9. If you need to separate the fuel pump and sensor, retract the fuel pump into the rubber connector and slide the pump off the bottom support. Care must be taken not to damage the rubber insulator and fuel filter during removal. After removing the pump from the bottom of the support, pull the pump out of the rubber connector.
Installation
10. Position the rubber gasket around the fuel tank opening and install the fuel pump and gauge into the tank.
11. Turn the inner retaining ring clockwise until the locking stops are fully engaged with the shanks.
Note. Since you installed a new o-ring, it may be necessary to press down on the inner circlip so that the latches go under the shanks.
12. Install the fuel tank (see section 5).
