- pipeline 1.5 m long with a diameter of 8 mm or 10 mm (the fuel line will need to be cut to the required length).

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