14) Fuel system
14.1) Description of system
See Ill. 30.
The fuel flows from the tank via a coarse filter/water trap Q to the two electric fuel
pumps W connected in parallel. From the pumps fuel passes on via the fuel pressure
control E to the two carburetors.
Via the return line T surplus fuel flows back to the fuel tank and suction side of fuel
system.
◆ NOTE: The fuel pressure control ensures that the fuel pressure is always
maintained approx. 0,25 bar above the variable boost pressure in the
"airbox" and thus ensures proper operation of the carburetors.
On the standard version of the engine the fuel lines from fuel pressure control to the
carburetors have already been laid.
The fuel system from tank to the fuel pressure control has to be installed by the aircraft
builder.
The fuel system includes the following items:
