7.2) Fuel system
General note See Fig. 2
Fuel The fuel flows from the tank (1) via a filter/water trap (2) to the two
electric fuel pumps (3) connected in series. From the pumps fuel
passes on via the fuel pressure control (4) to the two carburetors
(5).
NOTE: Parallel to each fuel pump a separate check
valve (6) is installed.
Fuel pressure con-
trol
The fuel pressure control ensures that the fuel pressure is always
maintained approx. 0.25 bar (3.63 psi) above the variable boost
pressure in the “airbox“ (8).
Return line
Via the return line (7) surplus fuel flows back to the fuel tank.
The return line must not present flow resis-
tance. Pay attention to possible constriction
of diameter or obstruction, to avoid overflow-
ing of carburetors.
