Flammable - Keep fire away; Make no fires around the work area, and handle the fuel carefully very much. Catching a fire to fuel will cause a serious accident.

Relieve the fuel pressure before the fuel line disconnection to avoid a risk for fuel blowing from there.

Disconnect the 12 volt battery negative terminal before the electric connector disconnection to avoid a risk for catching fire which is caused by the sparks coming off the connector.

Clean the contact area of the joint. Any dirt may cause fuel leakage by a misconnection.

Do not apply the brake fluid, engine coolant, plant-based oil, or alcohol-based oil to the O-ring. An undesignated fluid or oil may affect material deterioration or damage.

Follow the instructions, or you will not be able to take a quality guarantee for the parts.
