7.16 Fuel System
System Description
Fuel is supplied to the engine depending on the FUEL selector valve position ( LEFT - RIGHT - OFF ). To select the left
tank rotate the knob to position “A” or to select the right tank rotate the knob to position “B”. To shut off the fuel
val ve, lift the lock “D” and rotate the knob to position “C” ( Fig. 7-24).
Fig. 7-24 Fuel selector
From the left fuel tank the fuel flows through the coarse fuel filter, fine filter and the electric fuel pump (by-passed
with check valve) to the
FUEL selector valve inlet. From the right fuel tank, the fuel flows through the coarse fuel filter
and fine filter to the FUEL selector valve inlet. From the FUEL selector valve the fuel flows to the engine driven fuel
pump and then to a distributor inlet. One of distributor's outlets is connected to carburetors through the fuel flow
meter sensor and 3-way distributor. Fuel flow meter measures only the fuel consumed by the engine. Second one is
fitted with a restrictor jet to which a return line is connected. Return line leads back to the left fuel tank only.
Fuel pressure sensor and analogue fuel pressure indicator are installed in the fuel system and connected through
the 3-way distributor with restrictor jets in its outlets to the 4-way distributor. Both check the actual pressure in the
fuel supply line. Fuel pressure data from sensor are processed and displayed by Dynon SkyView SV-D1000.
The wing fuel tanks are connected with the fuselage wing tanks using a simple hose connection with clamps. Fuel
tanks are vented from the highest point and discharge through hoses protruding under the aircraft through the
fuselage skin inside of the center tunnel.
Fuel system diagram is shown at Fig. 7-25.
