3.6 Fuel System Maintenance
Periodically inspect all primer bulbs, connections, clamps and hoses for leakage and damage or
deterioration. Replace as necessary. Spray the valves, tank fuel gauge sender and ground
connections with a metal protector.
Frequently inspect and lubricate the fuel fill cap O-ring seals with petroleum jelly or silicone grease.
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.
Be sure that the fuel tank vent hose is properly routed and attached when the vents are 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 affect 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 degradation and fuel stabilizers recom-
mended 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 separation" 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
will worsen as the alcohol content increases. Water or a jelly like substance in the fuel filters is an
indication of phase separation from the use of alcohol blended fuels.
DO NOT DRAIN ANY FUEL INTO THE BILGE. THIS COULD LEAD TO A
FIRE OR EXPLOSION.
AFTER THE FILTER ELEMENT HAS BEEN CHANGED, PRIME THE FUEL
SYSTEM AND CHECK ALL FITTINGS FOR LEAKS BEFORE AND AFTER
STARTING THE ENGINES.
