CHECKING AND FILLING FUEL TANK
Be sure the engine is located on a level surface before checking
or refilling fuel. Use unleaded regular, unleaded premium
automotive fuels only. Commercial fuel may contain up to
10% ethanol. Ethanol additives to fuel are known to cause
deterioration of fuel lines and other fuel components. Viper®
recommends the addition of fuel stabilizer to protect your
engine's fuel system and prolong the life of your engine. DO
NOT mix oil with fuel.
1. Make sure engine is cool and not running while filling.
2. Remove fuel cap.
3. Fill tank to fuel level limit. SEE FIGURE 2
Note: Do not overfill. Leave room for fuel expansion.
4. Replace cap and remove any spilled fuel before operating.
