MENTS
The MV8 engine
features a fuel pump that is mounted in a capsule installed directly in the fuel tank. This
is similar to what is found in late model passenger cars and has proven through the
years to be reliable while offering superior performance.
Because the system found on your boat has been developed for use specifically in
a marine environment, a number of safety measures are incorporated in the entire
fuel system from tank to lines to connections. Please note that, as a result of
the pressurized fuel lines, there are no user-serviceable parts. Any ser-
vice required in the fuel system must be performed by authorized service person-
nel only as they will have the specialized tools and replacement parts that meet the
manufacturer's OEM specifications.
The fuel line that runs from the fuel tank to the engine is a special multi-layer ar-
mored line, covered in special fire retardant material call a "fire sleeve." The sleeve is
bright orange for immediate identification of the line. ILMOR recommends a daily
inspection to ensure that the line is not leaking. Never start the boat if there is evidence
of fuel leaks or fumes.
Be certain to read carefully the boat manufacturer's Owner's Manual section on
fueling for additional information and details. This is a critical component of safe and en-
joyable boating.
Gasoline is explosive. If a gasoline odor is present or if gasoline can be seen at any
point along the fuel line, the fuel tank, in the bilge or at the engine, DO NOT START
THE ENGINE! Remove the key from the ignition switch and call an authorized boat
and/or ILMOR dealer for service. Take care not to spill gasoline when fueling. If gas
is spilled accidentally, wipe up all traces with dry rags immediately and dispose of
properly on-shore.
Careful inspection of the entire fuel system for leaks and/or deterioration must be
part of the maintenance of the engines prior to each outing. This inspection becomes
even more critical after substantial periods of non-use or storage. Be certain the in-
spection includes the fuel tank, fuel lines, fuel pump, regulator, fuel rails, carbon can-
isters and all fittings in the system. Any component that shows even slight signs of
corrosion, leakage, deterioration, swelling, hardening or softening should be brought
to the attention of an authorized ILMOR and/or boat manufacturer's dealer for re-
placement prior to using the boat.

octane fuel. The octane number is based on the pump octane number, which is (R + M)/2,
where R is the research octane number and M is the motored octane number.
For better performance, 93 octane fuel is recommended.
Fuels other than specified will negatively alter performance, emissions and could dam-
age the engine. Use of lower octane fuels will cause spark knock (pinging). Continued heavy
