7.6 Fuel system
The fuel system (see
) includes two wing fuel tanks (1,2), fuel lines
(5,6,9,10,12,14,16,18,20,21,22), two shut-off valves (7,8), fuel sediment collector (13), fuel
filter (15), fuel pump (19), return line (26), drain line (27) and drain valve (28). The fuel tanks
(11.9 (15.05) US gal each) are located at the wing root between the spar and aft web. The
fuel inlet 3(4) is located at the front outboard corner of the tank. The inlet cover has vent
fitting 30(31) connecting the tank volume free of fuel to the atmosphere. The fuel shut-off
valves (7,8) are located on the vertical beams of the frame No.3, on the left and right sides
respectively. The shut-off valve is open when its handle is set vertically and closed when the
handle is set horizontally. The left and right fuel tank is connected with the fuel lines to the
left and right fuel shut-off valve respectively. Further two fuel lines are joined into a single
one with the T-connector (11), which is located near the web of the frame No.4 at its bottom
part. Then fuel goes to the fuel sediment collector (13). The top outlet of the fuel sediment
collector is connected to the fuel filter (15) located on the right side behind the main landing
gear beam. The fuel filter can be inspected visually through a window in the protecting cover
of the aileron control cables. The bottom outlet of the fuel sediment collector is connected
to the drain valve (28) with a drain line (27). The drain valve allows draining fuel through the
hole in the bottom rear panel of fuselage. The valve handle is accessible outside of the
fuselage. After the fuel filter the fuel line (16) runs through the main landing gear beam, seat
beam along the right-hand side of fuselage to the firewall where it is connected with a 90°
bulkhead fitting (17), that is passing through the hole in the firewall, to the fuel line of the
engine (18) and is connected to the inlet of the fuel pump (19) located on the right-hand side
of the engine gearbox. The pump outlet is connected with the fuel lines (20,21,22) to the
carburetors (23, 24). The excessive fuel is returned through the line (26) to the sediment
collector (13).
Standard
Optional
Capacity of tanks:
2×45 l (11.9 US gal) 2×57 l (2×15.05 US gal)
Total fuel capacity:
90 l (23.8 US gal)
114 l (30.1 US gal)
Total usable fuel:
88 l (23.3 US gal)
112 l (29.6 US gal)
Non-usable fuel:
2 l (0.5 US gal)
2 l (0.5 US gal)
NOTE: When both tanks are full, fuel may flow from one tank to the other (e.g. due to the
lateral forces during side slipping or when wings are not level on parking or during
taxiing), overfill it and spill out through the vent line. To prevent this close one of the
fuel valves.
