Rules of Cleanliness
WARNING:- Always disconnect the negative (-) battery cable and cover the terminal with an insulated material whenever working on any fuel related component.
- Gasoline is dangerous to your health. Wear hand and skin protection when working on the fuel system. Do not breathe fuel vapors and always work in a well-ventilated area.
- Fuel and fuel vapors will be present during many repair procedures. Do not smoke or create sparks. Have an approved fire extinguisher handy
- The fuel supply system is designed to maintain pressure in the system after the engine is turned off. Fuel will be expelled under pressure as fuel lines are disconnected. This can be a fire hazard, especially if the engine is warm. Always wrap a clean shop rag around the fitting before loosening or disconnecting any fuel line.
CAUTION:
- Cleanliness is essential when working on the fuel system. Thoroughly clean fuel line unions and hose fittings before disconnecting them. Use only clean tools.
- Use only spring-type fuel hoses. Do not use screw-type hose clamps.
- Keep removed components clean, and seal or cover them with plastic or paper, especially it the repair cannot be finished immediately.
- When replacing parts, install only new, clean components. Seals and O-rings should always be replaced rather than reused.
