General information on the fuel system

The most common reason for engine failure is a fault in the fuel system. Many
problems can be prevented by regular checks. Contamination and formation of
condensate can lead to erratic engine running or misfiring.
- Check float chamber for dirt and water.
- In the event of serious contamination or water, drain, clean and flush the
whole fuel system thoroughly, including the tank, filter, fuel pumps, float
housing and fuel lines.
■ CAUTION :
- Unsuitable routing of fuel lines may cause engine failure.
- After repair work, the fuel system must be checked for leaks.
- Always use clean and non-translucent, safety approved fuel containers. Do
not smoke, do not allow open flames or sparks in the vicinity.
- Never refuel with engine running.
- Do not fill the tank to the brim, allow for expansion of the fuel.
- Remove spilt fuel immediately, dispose of it respecting environmental
regulations.
- Gasoline is highly inflammable and under certain conditions explosive.
Handling of fuel in well ventilated places only.
- Close fuel cock, as the float needle valve may not retain the fuel pressure
over a longer period or during transport of the aircraft.
