Electric Fuel Pumps
22825-a
EFI engines have two electric fuel pumps:
● A high-pressure pump A to supply the fuel injec-
tors.
● A low-pressure pump B to bring fuel from the boat
tank to the engine.
Both pumps are protected by a single 20-amp fuse and
relays. The pumps will operate only when the engine
is cranking or running. If a pump does not function,
check the fuses and replace them if necessary. See
your Volvo Penta dealer if further service is required.
NOTICE! A loud whining noise at idle may be due to
a restricted fuel filter causing a noisy fuel pump. Oper-
ating the engine with a restricted filter may damage the
pressure regulator or fuel pumps. See your Volvo
Penta dealer if the pump makes an unusual noise.
