explosive under certain conditions.
• When you remove any fuel system
component to perform maintenance
(such as changing the fuel filter) place
an approved container under the
opening to catch the fuel.
• NEVER use a shop rag to catch the
fuel. Vapors from the rag are extremely
flammable and explosive.

component.
• Failure to comply will result in death or
