Fuel cell

Attention: The fuel tank volume must be measured and adjusted
before the first competition to ensure that the capacity does not
exceed that stated by the relevant regulations.
Both the main and reserve fuel pumps are of the electrical vane type.
The fuel filter is located in the front luggage compartment and should be
replaced after approximately every 24 hours of use. A scavenge filter
element is mounted before the pump which should be cleaned after every
race. The fuel system can be drained from the quick release coupling
mounted on the left hand side of the engine bay.
