Maintenance EFI models: Some marinas sell fuel with lead addi- tives. Do not use leaded fuel, as it may block the fuel injectors and cause leakage. DANGER! Fuel leakage can contribute to a fire and/or explosion. Frequently inspect non- metallic parts of the engine’s fuel system and replace if excessive stiffness, deterioration, or fuel leakage is found. 22823 To prevent fire and explosion, perform all service pro- cedures with the engine turned OFF. Failure to inspect your work may allow fuel leakage to go undetected. This could become a fire or explosion hazard. After completing service procedures, start en- gine and check entire fuel system for possible leaks.
To prevent fire and explosion, Volvo Penta fuel sys- tem components meet U.S. Coast Guard require- ments for fuel and fuel vapor containment. Do not substitute automotive or other non-approved parts. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 Carburetor (GL) The carburetor vaporizes fuel and mixes it with air in proper quantities to suit the varying needs of the en- gine. Except for changing the carburetor fuel filter screen, the carburetor requires no periodic mainte- nance or adjustment. If operational problems occur, see your Volvo Penta dealer.
Electronic Fuel Injection (Gi, GXi) The electronic fuel injection (EFI) fuel metering sys- tem delivers the correct amount of fuel to the engine under all operating conditions. The EFI system is con- trolled by a microprocessor, and requires no periodic maintenance or adjustment. If operational problems occur, see your Volvo Penta dealer. Flame Arrestor Remove the flame arrestor every 50 operating hours. Clean in solvent, air dry, and inspect it for dam- age. Replace if damaged. Reinstall flame arrestor; make sure unit is securely fastened. To prevent fire and explosion in the engine compart- ment, the flame arrestor must always be in place, properly secured, and undamaged.
For 8.1 L engines: Use compressed air to clean out the flame arrestor. 21212 VPA 7743722 English 10-2004 71
