3.5 Fuel System Maintenance

Periodically inspect all connections, clamps and hoses for leakage and damage or deteriora-

tion. Replace as necessary. Spray the valves, fuel gauge senders and ground connections with

a lubricant/protector.

Frequently inspect and lubricate the fuel fill cap O-ring seal with petroleum jelly. The O-ring

seal prevents water from entering the fuel system through the fuel fill cap and it should be

immediately replaced if there is any sign of damage or deterioration.

Periodically, remove the fuel vent and clean corrosion and salt buildup from the vent screen.

The screen will prevent insects and other foreign matter from contaminating the fuel and fuel

system. The fuel vent should be replaced if the vents or screen is damaged or badly corroded.

A fuel vent screens that is clogged will prevent the fuel tank from venting properly and make

filling the fuel tank difficult or cause fuel supply problems to the engine.

Be sure the screen is secure and that the fuel tank vent hose is properly routed and attached

when the vent is reinstalled or replaced. The fuel tank vent hose must be looped above the

vent, secured to the hull near the vent and securely attached to the vent hose fitting with two

hose clamps.

The age of gasoline can effect engine performance. Chemical changes occur as the gasoline

ages that can cause deposits and varnish in the fuel system as well as reduce the octane rating

of the fuel. Severely degraded fuel can damage the engine and boat fuel tank and lines.

Therefore, if your boat is not being run enough to require at least one full tank of fresh fuel

a month, a fuel stabilizer should be added to the gasoline to protect the fuel from degradation.

Your dealer or the engine manufacturer can provide additional information on fuel degrada-

tion and fuel stabilizers recommended for your engine.

Avoid using fuels with alcohol additives. Gasoline that is an alcohol blend will absorb

moisture from the air which can reach such concentrations that "phase separa-

tion" can occur whereby the water and alcohol mixture becomes heavy enough

to settle out of the gasoline to the bottom of the tank. Since the fuel pick up tube

is very near the bottom of the tank, phase separation can cause the engine to run

very poorly or not at all. This condition is more severe with methyl alcohol and
