ATTENTION
Fuels containing alcohol always carry a small amount of water
in solution. In case of temperature changes or increase of alco-
hol content, water or a mixture of alcohol and water may settle
and could cause troubles.
Water in fuel will accumulate at the lower parts of the fuel sys-
tem and leads to freezing of fuel lines, filters or jets.
Remedy
• Use non-contaminated fuel (filtered through suede)
• Generously sized water separators
• Fuel lines routing inclined
• Prevent condensation of humidity, i. e avoid temperature dif-
ferences between aircraft and fuel
