Replacing a part of the fuel line
Cutting off the old fuel line
1. Allow the engine to cool for at least an hour before starting work.
2. Disconnect the negative battery terminal.
3. Measure the diameter of the fuel line to select the appropriate parts and tools.
4. If the fuel line is cut under the bottom of the vehicle, then to prevent fuel from draining from the tank, it is necessary to either disconnect the fuel line or remove the fuel from the tank.
5. The location of the cut will determine the position of the joint. In this regard, the following conditions must be met:
- the cut must be straight;
- the fuel line connection must not be located closer than 50 cm to the catalytic converter, above high-heat areas or electrical connectors, on lines between the engine and the body, in the area between the engine and the catalytic converter.
6. When installing connections on parallel pipelines, it is necessary to select the cut locations so that the connecting sleeves are subsequently located relative to each other with some offset.
7. To avoid damaging the two sealing rings of the coupling and to ensure a perfect seal of the joint, a special pipe cutter (6) must be used to cut the pipeline.
Cutting the new fuel line
If the section of fuel line to be replaced does not have any specific connections and is a straight section, a 1.5 m long line supplied as a spare part can be used.
To ensure proper cutting, place a section of the old fuel line on the new one and mark the cut location.
Cut the pipeline using a special pipe cutter.
Installing the coupling
1. Install the coupling directly onto the pipelines and press firmly.
2. Connect the battery.
3. After installing all connecting couplings, it is necessary to check the tightness of the fuel lines:
- for pressure pipelines (gasoline supply) run the engine for five minutes to ensure there are no leaks around the new connections;
- for vacuum fuel lines (diesel fuel supply) run the engine for five minutes and make sure there are no air bubbles in the transparent pipe at the outlet of the high-pressure fuel pump.
Removal the coupling sleeve
1. Allow the engine to cool for at least an hour before starting work.
2. Disconnect the negative battery terminal.
3. If the fuel line is disconnected under the bottom of the vehicle, then to prevent fuel from draining from the tank, it is necessary to either disconnect the fuel line or remove the fuel from the tank.
4. Remove the coupling sleeve using special pliers with a diameter of 8 mm or 10 mm (Legris and Raymond) (7), corresponding to the diameter of the fuel line.
