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. A camshaft-
driven fuel pump is also located internally in the engine.
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 the pump-in-tank
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.
The Malibu fuel system
from tank to plumbing to engine meets or exceeds U.S. Coast Guard
requirements (Sec. 183.540 Recreational Boating.) Because of the potential
for a dangerous, even catastrophic event if any part of the system fails,
Malibu strongly encourages all owners/operators to always be aware of
proper operation. Follow operational directives, maintenance requirements
