Before removing fuel line components, perform the following procedures:
- Collect the drained fuel in an explosion-proof container and close it tightly with a lid. Store the container in a safe place.
- Release residual pressure in the fuel line (see chapter "Engine management system").
- Disconnect the negative battery terminal.
- Always replace O-rings and clamps with new ones.
- When installing fuel lines, do not bend or twist them.
- Do not overtighten the clamps to avoid damaging the hoses.
- After connecting quick-release connectors, check their reliability.
Check that the connector and plastic tubes do not touch adjacent parts.
After connecting the pipelines, check the tightness of the connectors:
- Create pressure in the fuel lines by turning on the ignition, but without starting the engine. Then check if fuel is leaking at the pipe connections.
- Start the engine, increase the speed and check for leaks in the connectors.
When replacing the fuel filler cap, use only a genuine NISSAN cap. Installing any other cap may cause the MIL to come on.
