Fuel Systems<br />
! WARNING !<br />
Fuel leaking from any part of the fuel system can<br />
lead to fire and explosion that can cause serious<br />
bodily injury or death. Inspect system before<br />
fueling.<br />
! CAUTION !<br />
Using the wrong type of fuel will result in severe<br />
damage to the engines. Refer to your owner’s<br />
manual for fuel recommendations.<br />
! DANGER !<br />
Leaking fuel is a fire and explosion hazard.<br />
Personal injury or death could occur.<br />
5.2 Fuel Supply Lines and Hoses<br />
If any fuel fill or vent hose's are in need of replacement,<br />
ensure that only USCG Type A1 or A2 are used. The<br />
engine has a fuel supply hose that runs from the pickup<br />
tube in the fuel tank to the fuel water separator (commonly<br />
referred to as the fuel filter), then from the filter to<br />
the engine. Also, the engine has a fuel return hose that<br />
runs from the engine back to the fuel tank. If your boat<br />
has a generator, the generator will have somewhat the<br />
same setup, with the supply and return hose. The fuel<br />
supply lines or hoses, fitting, and connections should be<br />
inspected often for leaks and signs of wear, dry rot, chafing,<br />
or swelling. A good way to inspect the fuel hoses is<br />
to run your hand along the length of the hose including<br />
the fittings. Leaks will be revealed as wet spots on your<br />
hand. If any evidence of hose deterioration is present,<br />
have a qualified technician replace all the hoses with<br />
USCG Type A1 hoses immediately!<br />
5.1.3 Fuel Tank Fill & Vent<br />
The fuel tank fill fitting is located on the stbd. side on the<br />
stern. The fuel tank also has a hull vent fitting. This fitting<br />
is also located on the stbd. side near the fuel fill. You can<br />
see the fill in detail in Fig. 5.2, on page 5.3.<br />
The fuel tank vent serves as a pressure / vacuum release<br />
and a safety overflow. The vent is a thru hull fitting<br />
with a flame arrestor, so it is imperative that you keep<br />
the screens clear and in excellent repair. Replace the<br />
screen immediately if it becomes damaged or displaced.<br />
Periodically check the vent to see that it is not clogged.<br />
The fuel fill and fuel vent hoses, fittings, and connections<br />
should be inspected for leaks and signs of dry rot<br />
or swelling at least once a year. If any of these conditions<br />
are present, have an authorized service technician<br />
inspect the fuel system immediately. If a leak is found,<br />
turn off battery switches, disconnect shore power, and<br />
disable any possible source of ignition. Contact your<br />
dealer or Customer Service immediately.<br />
! DANGER !<br />
The use of any hose other than the USCG Type A1<br />
or A2 could result in fuel leakage. Leaking fuel is a<br />
fire and explosion hazard. Personal injury or death<br />
could result.<br />
In Fig.5.3 you can see the fuel supply fittings. The photo<br />
inset shows the close-up of the fuel valve. See Fig.5.5<br />
for the function of the fuel valves.<br />
Note: If a leak is found, turn off battery switches, disconnect<br />
shore power, and disable any source of ignition. Do not start<br />
your engines, the generator, or any devices that could create<br />
a spark. Contact your dealer or our Customer Service<br />
Department immediately! If hoses need to be replaced, make<br />
sure only USCG Type A1 are used.<br />
5.2.1 Generator Fuel Supply Notice<br />
In Fig. 5.4 we demonstrate the layout of your boat's<br />
fuel pick up lines in the fuel tank. See the Mechanical<br />
Arrangement Drawing in the Boating Safety chapter of<br />
this manual for more location information. In the image<br />
you can see the pick up for the generator is located<br />
higher than the engine pickup<br />
