Replacement
Attention:
- Do not smoke while working on the fuel system.
- Keep open flames away from the workplace.
- When replacing the fuel filter, be careful to keep it away from the battery terminals and other tools.
The fuel filter must be replaced if the fuel pressure drops below the specified value.
- Engines D14A3, D14A4, D15Z4, D15Z5: 226-275 kPa (2.3-2.8 kg/cm2).
- Engines D16Y4, D16Y9: 275-324 kPa (2.7-3.2 kg/cm2).
With the vacuum hose disconnected and clamped and after the fuel pump and return valve are in good working order,
1. Disconnect the negative battery cable.
2. Place wipes under and around the fuel filter.
3. Relieve fuel pressure.
4. Unscrew the special bolt and remove the fuel pipes using a wrench as shown in the figure.
5. Remove the filter clamp and the filter itself.

Note: Clean the pipe connections before assembly.
