Flame Arrestor

Clean the flame arrestor (1 or 2) every 50 operating
hours.
WARNING! Use extreme care when removing
flame arrestor on 8.1L engines (2). The elec-
tronic throttle plate, located behind the flame
arrestor, has moving parts that are sharp and
may severely cut or amputate fingers.
•
Clean in solvent, air dry, and inspect for damage.
•
Replace if damaged.
•
Reinstall flame arrestor; make sure unit is
securely fastened.
To prevent fire and explosion in the engine compart-
ment, the flame arrestor must always be in place,
properly secured, and undamaged.

Electric Fuel Pumps

WARNING! Check fuel pumps (A and B) fre-
quently for signs of fuel leakage. If leakage
occurs, have the fuel pump serviced immedi-
ately by your Volvo Penta dealer.
EFI engines have two electric fuel pumps:
•
A high-pressure pump (A) to supply the fuel
injectors.
•
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.
The pumps will operate only when the engine is crank-
ing 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! Do not run engine out of fuel or run the elec-
tric fuel pumps dry more than 20 seconds.
Running the electric fuel pumps dry will
damage the fuel pumps.
