Fuel Pressure Release: Service Precautions
WARNING! When removing and installing the fuel pump or fuel level sensor from a filled or partially filled fuel tank:
- Fuel supply lines are under pressure! Before removing, wrap a cloth around the connection. Then release pressure by carefully loosening line at connection.
- BEFORE beginning repairs, the suction pipe of an exhaust extraction system must be located near the fuel tank opening so that escaping fuel vapors can be immediately carried away.
- if no exhaust extraction system is available, a radial fan (motor located outside airflow) with volume of at least 15 cubic m/hr (9 cfm) may be used.
- Wear fuel-resistant gloves whenever working with open parts of the fuel system.
