malibu fuel system
All Malibu models are equipped with the most up-to-date fueling
system available in the marine industry. The boats feature pump-
in-tank (PIT) fuel systems, which means the fuel pump is located
securely inside the fuel tank rather than at the engine. There are
many benefits to the PIT system, most significantly in the prevention
of vapor lock and improved filtration of contaminants.
To maximize the benefit of this type of fuel pump, the entire
system is under high pressure. That means that access to the pump
and fuel filter is only through fuel lines with a significant pounds-
per-square-inch (PSI) pressure to ensure proper operation. As
such, no one can or should ever attempt to access any portion of
the fuel system without proper training and proper equipment.
The
fuel lines are covered in orange “fire-sleeve” protective
covering so that they are easily identifiable, and consumers
should always avoid these lines, unless it is noted that one
is squeezed or pinched.
If it is possible to alleviate this situation
safely, then do so. The preferable method, however, is to have an
authorized Malibu dealer’s trained service technician do so and verify
that no damage has been done to the line or other equipment.
Normally, if there is any issue arising from damage or leakage in
the fuel system a strong odor of gasoline will be present and signifies
that the engine should not be started due to the danger of explosion
from fumes. Even in the absence of a gasoline odor, owners and
operators should always visually check the fuel system prior to
operation, as directed in the
Care and Maintenance section of this
Owner’s Manual.
The fuel system, including
the fuel lines, filter and
pump, should never be
serviced by any person
other than an authorized Malibu dealer’s trained service
technician. Special tools and training are required to
safely service the fuel system on all models.
The flammability of
gasoline and its explosive
properties must always be
respected. At the first odor
of gasoline, the engine should be shut off and remain off
until the source of the odor has been identified and the
issue has been rectified.
Never smoke or operate
any spark-producing object
within a fifty-foot (50’) range of the boat when fueling.
Fumes from gasoline are more likely to produce an
explosion and/or fire than the actual fuel.
If fuel is spilled, always
clean up with dry rags and
dispose of properly on-
shore.
Review the engine
manufacturer’s owner’s
manual or the
Engine section
of this Owner’s Manual
where appropriate, for important information regarding
the proper fuel to use, how to maintain the fuel if the
boat will not be used for a period of time, and other
important information regarding the safe use of gasoline
in the boat.
Use of incorrect fuel can
result in damage to the
engine that is not covered by
the engine manufacturer nor
by Malibu. Failure to follow maintenance requirements
may also void the warranties.
Malibu recommends returning to shore and refueling whenever
the fuel gauge indicates that the fuel load has fallen below
one-quarter (1/4) of a tank full.
It has been determined that
continuous operation with ballast significantly loaded either
port or starboard (rather than evenly distributed) can result in
damage to the fuel pump as it attempts to compensate.
Also,
even with the best of care, some water may get into the fuel tank or
separate from the fuel that is pumped into it. If there is water present,
it will settle on the bottom of the tank. If the pump begins to reach any
water, it may cause malfunctioning in the engine.
When pumping fuel, do not leave the nozzle unattended in
the fuel fill. Although the fuel system has been manufactured to
avoid spit-back of fuel, and most gasoline dispensers will shut off if
removed from fuel fill, it is always a wise consideration to provide full
attention to the process.
