Section 3 Fuel System
OS 385
Try not to spill fuel. If fuel is spilled, wipe up
all traces with dry rags and immediately dis-
pose of the rags properly onshore. DO NOT
allow fuel to stay on the finish of the boat,
discolor and damage to trim can occur.
Avoid fueling at night, except under well-
lighted conditions. Also, monitor fuel level
gauge to avoid overfilling.
To fill fuel:
1. Turn all switches to "OFF."
2. Secure boat.
3. Remove passengers from boat.
4. Extinguish all flame producing items.
5. Open fuel fills with fuel fill key, counter-
clockwise.
6. Put nozzle in the fuel fill opening.
7. Fill the fuel tanks slightly less than rated
capacity to allow for expansion.
8. Remove the nozzle.
9. Install and tighten fuel cap. Do not to
overtighten.
10. Check the fuel compartment and below
the deck for fuel odors. If you smell fuel,
DO NOT start engines.
3.5 Fuel System Maintenance
Spray the valves, fuel tank gauge sender
and ground connections with a metal protec-
tor.
Inspect the fuel fill cap o-ring seals fre-
quently and lubricate with petroleum jelly or
silicone grease. The o-ring seal prevents
water from entering the fuel system through
the fuel fill cap. If the o-ring is damaged, or
you suspect it is damaged, replace it.
Old, degraded gasoline can affect engine
performance and damage the engine and
boat fuel system. Chemical changes occur
as gasoline ages, reducing octane and can
cause deposits and varnish in the fuel sys-
tem.
If your boat is not operated enough to
require at least one full tank of fresh fuel a
month, a fuel stabilizer should be added to
the gasoline to protect the fuel from degrad-
ing. Do not allow the boat to sit unused for
an extended period with the fuel tanks less
than 3/4 full. Changes in temperature and
weather conditions can cause condensation
in fuel tanks. Your Pursuit dealer or the
engine manufacturer can provide additional
information on fuel degrading and fuel stabi-
lizers recommended for your engine.
Improper storage of fuel at marinas, limited
boat usage, etc. can cause the fuel to
become contaminated. Periodically, it may
be necessary to pump accumulating water
and contaminated fuel from the bottom of
the fuel tanks. If the fuel system on your boat
becomes contaminated, contact your dealer
or marina for assistance.
Avoid using fuels with alcohol additives.
Alcohol blend gasoline will absorb moisture
from the air which can reach such concen-
trations that "phase separation" can occur
where the water and alcohol mixture
becomes heavy enough to settle out of the
gasoline to the bottom of the tank. Since the
fuel pickup tubes are near the bottom of the
tank, phase separation can cause the
engine to run very poorly or not at all. Phase
separation is more severe with methyl alco-
!
CAUTION
Use only the fuel recommended by the
engine manufacturer. Use of old, con-
taminated fuel can cause the engine to
malfunction or severe damage. Do not
use fuel that contains more than 10%
ethanol, harsh additives or methanol;
damage to the engines and fuel sys-
tem will result. Fuel system damage,
related to use of alcohol-blended
fuels, is not covered by the Pursuit
Limited Warranty. Refer to the engine
owner's manual for specific fuel
requirements for your engines.

DANGER
FIRE / EXPLOSION HAZARD
Fuels are extremely flammable and
highly explosive under certain condi-
tions. DO NOT smoke or allow open
flames or sparks nearby when
inspecting the fuel system.
Frequently check fuel lines and all
system components (filters, primer
bulbs, clamps and connections) for
leaks, damage or deterioration, or if
you suspect damage, replace as nec-
essary. Surface cracking on a hose
indicates wear. Replace it.
