Revision : 1.3
The aircraft has two fuel tanks, one located in the inside leading edge of
each wing.
Volume of wing tanks: 2 x 84 (22.19 US gallons) litres (168 litres (44.38 US
gallons) total, 164 (43.32 US gallons) litres useable).
Each tank is equipped with a vent outlet. A drain valve is located in the
lowest point of the each tank. A tank outlet / fuel pick-up is located at the
lowest point of the inboard sidewall of each tank. A finger screen is fitted
to each fuel pick-up. An inline mesh fuel filter is fitted in the fuel line from
each tank to the fuel tank selector valve, which is mounted on the lower
centre instrument panel (in the cockpit, refer to paragraph 7.12).
Fuel feed is through two electric pumps. Each pump has a parallel installed
check valve (NRV).
The fuel feed from the fuel pumps enters a fuel pressure controller
mounted on the engine, whereafter it splits into two separate branches,
one for each carburettor. A fuel pressure sensor is connected to one fuel
pipe branch. A fuel flow sensor is connected in the one fuel pipe branch.
The sensors are connected to the EFIS via the RDAC unit.
Fuel return lines return excess fuel supplied by the fuel pump(s) to the fuel
tank in use.
