Precautionary measures
- Do not smoke while working on the fuel system.
- Avoid open flames in the workplace.
The fuel hose assembly with quick-release couplings serves to connect the fuel line and the fuel pump built into the gas tank. To remove or install the pump or gas tank, it is necessary to disconnect or connect the quick-release couplings. In this case, pay attention to the following:
- The fuel hose with quick-release couplings is not a heat-protected assembly;
- Be careful not to damage these parts during welding or other thermal work.
The fuel hose with quick-release couplings is not acid-resistant. Do not touch these parts with cloths or rags that were used to wipe the battery. Replace the fuel hose with quick-release couplings if they come into contact with electrolyte or similar substances.
When connecting or disconnecting, do not bend or twist the hose excessively. Replace it if damaged.
A disconnected quick-connect fitting can be reconnected, but the latch on the inner tube cannot be reused if it has been removed from the tube. Replace the latch if:
- replacement of the fuel pump.
- replacement of the fuel line.
- in case of removal from the branch pipe.
- in case of damage.
Disconnection
Do not smoke while working on the fuel system. Keep open flames away from the work area.
1. Disconnect the negative terminal from the battery.
2. Remove the tank cap to relieve vapor pressure in the tank.
3. Relieve the fuel pressure in the system.
4. Inspect the quick release coupling for dirt and wipe clean if necessary.
5. Hold the connector with one hand and press the latch buttons with the other, then pull the pipe out of the connection.
Note:
- Be careful not to damage the tubes or other parts. Do not use tools.
- If the hose does not come out of the connector, hold the latch buttons down and periodically move the connector in/out until it comes loose.
- Do not remove the latch from the pipe; once removed, the latch must be replaced.
6. Check the contact area of the pipe for contamination or damage.
If the surface is dirty, clean it.
If the surface is rusted or damaged, replace the fuel pump or fuel line.
7. To prevent damage and contamination, cover the ends of the tubes with plastic bags.
Note:
The latch cannot be reused if it has been removed from the nozzle.
Replace the latch if:
- fuel pump replacement,
- replacement of fuel lines,
- in case of removal from the branch pipe,
- in case of damage.
Compound
Do not smoke while working on the fuel system. Keep open flames away from the work area,
1. Check the contact area of the pipe for damage and contamination, clean if necessary.
2. Install a new latch + into the connector if the latch is damaged or if:
- fuel pump replacement,
- replacement of fuel lines,
- in case of removal of the spartubka.
Before installing the new hose/quick disconnect assembly, remove the old latch from the fitting.
3. Align the quick-release coupling with the pipe and align the tabs of the latch with the slots of the connector. Then push the pipe into the coupling until both tabs lock with a distinctive click.
Note: If it is difficult to push the hose into the joint, lubricate the end of the hose with a small amount of engine oil.
4. Make sure the connection is secure and the protrusions are securely fastened in place. Check visually and by trying to remove the pipe from the connection.
5. Reconnect the cable to the negative terminal of the battery and turn on the ignition. The fuel pump will operate for two seconds and the fuel pressure will increase. Repeat the activation two or three times and check the system for leaks.
