Possible Causes

• No fuel in tank.
• Fuel supply line could be broken or crimped.
• Fuel could be jelled (most likely in cold weather with No. 2 fuel).
• Pick-up tube screen in tank could be clogged.

Cloudy fuel indicates that fuel may not be a suitable grade for cold temperatures; excessive water or contaminants may indicate that tank and fuel system may need to be flushed and cleaned.
