7.10.8 FUEL SELECTOR VALVE
A rotary fuel selector valve is mounted behind the firewall on the right side of the fuselage. A
torque tube connects the valve to the cockpit handle. Pull and turn the handle 90° to open
the valve to the Acro & Center tank. A further 90° turn switches to the Wing tank fuel supply.
Position down = CLOSED
Position left = ACRO & CENTER TANK
Position up = WING TANK
7.10.9 EXHAUST SYSTEMS (OPTIONAL)
Optionally the EA 300/S can be equipped with an additional silencer system type Gomolzig.
The attachment is integrated in the fuselage structure. Thus no modifications are necessary
to install the silencer system.
Alternatively a complete 6 in 1 System with integrated silencer is available.
7.11 FUEL SYSTEM
The fuel system consists of two separate, independent tanks:
- Acro & Center tank in the fuselage
- Wing tank (LH and RH)
Wing tank:
The root section of each wing - in front of main spars forms an integral fuel tank providing
two interconnected tanks with 120 liters (31,7 US GAL.) total capacity. Each side of the wing
has a 2" diameter filler cap for gravity refueling. The wing tank can be completely emptied in
flight but the normal amount of unusable fuel is approximately 2 Liters
(0.5 US Gallon).
Acro & center tank:
An Acro tank 9 liters (2,3 US Gal.) is mounted in the fuselage just behind the firewall and the
Center tank 42 liters (11,1US Gal.) just behind the main spar of the wing. The Acro tank is
connected with the center tank in a gravity feed system. The center tank has a 2" diameter
filler cap for gravity refueling. Unusable fuel is approximately 2 liters (0,5 US Gal.)
Adequate venting is provided in each tank to a main ventilation-tube, ending outside the
fuselage at the right side.
In addition to the engine driven fuelpump an electrically driven auxiliary fuel pump (boost
pump) with by-pass and having sufficient capacity to feed the engine at take-off power is
fitted as a safety device against failure of the engine-driven pump. The boost pump switch is
located on the instrument panelt.
A fuel filter with drain is installed between the fuel selector valvef and the boost pump.
Separate drains are located at the lowest point of each tank system.
Normal float type transducers and electrically operated fuel indicators are used.
