Axis Wake Research A20 - Axis Fuel System

All Axis 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 benets to the PIT system, most signicantly in the
prevenon of vapor lock and in the improved ltraon of contaminants.
To maximize the benet of this type of fuel pump, the enre system is high pressure. That means that
access to the pump and fuel lter is only through fuel lines that have a signicant pounds-per-square-
inch (PSI) pressure to ensure proper operaon. As such, no one can or should ever aempt to access any
poron of the fuel system without proper training and proper equipment. The fuel lines are covered
in orange “re-sleeve” protecve covering so that they are easily idenable, and consumers should
always avoid these lines, unless it is noted that one is squeezed or pinched. If it is possible to alleviate this
situaon safely, then do so. The preferable method, however, is to have an authorized Axis 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 signies 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 operaon, as directed in the Care and Maintenance secon 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 Axis 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 o and remain o 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 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 Axis.
Failure to follow maintenance requirements may also void the
warranties.
Axis 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 connuous operaon with
ballast signicantly loaded either port or starboard (rather than evenly distributed) can result in damage
to the fuel pump as it aempts 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 sele on the
boom of the tank. If the pump begins to reach any water, it may cause malfunconing in the engine.
When pumping fuel, do not leave the nozzle unaended in the fuel ll. Although the fuel system has
been manufactured to avoid spit-back of fuel, and most gasoline dispensers will shut o if removed from
fuel ll, it is always a wise consideraon to provide full aenon to the process.
