Fuel system
2 parallel electrical low pressure fuel pumps
each ECU has an associated fuel pump
(ECU A: pump A, ECU B: pump B)
normal Ops: only one pump working
when ECU switches over: fuel pumps switch
over as well
When pump fails (low fuel pressure):
automatic switch over to other pump by
switching to the other ECU
For TKOF, LDG and with fuel pressure failure:
both pumps switched ON manually with
FUEL PUMP switch
