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.
Circuit Breakers and Fuses
The engine’s electrical system is protected against cir-
cuit overload by fuses and circuit breakers.
Engine electrical circuits may also be routed through
relays.
All relays, breakers, and fuses for the driveline are
contained in a single fuse box. The box is covered and
is mounted on the top of the engine.
If electrical systems such as power trim or ignition are
not working, check this box as a first step in trouble-
shooting the problem.
