Section 3 Fuel Systems
Contaminated Gasoline
Water from condensation and sediment from contami-
nated gasoline can collect in your fuel tank. Contami-
nated gasoline can damage boat fuel system
components, corrode the fuel tank, clog fuel filters,
and damage your engines’ fuel systems.
Your fuel filter inspection and servicing routine is
directly related to the quality and quantity of gasoline
that you take on-board. You should check the fuel fil-
ter sight bowls for evidence of moisture before and
after every mission.
Refer to Blended Fuels in this section for more infor-
mation about water in gasoline.
It might become necessary to sample your gasoline for
evidence of moisture or particulate contamination.
Adjust the boat angle so that the lowest portion of the
fuel tank is below the fuel withdrawal tubes. If possi-
ble, let the gasoline “rest” for 30 minutes before sam-
pling.
Use one of the engine fuel supply hoses and primer
bulbs to pump the sample gasoline into a clean con-
tainer and inspect for moisture or particulate contami-
nation.
If the test sample shows evidence of moisture or par-
ticulate contamination, consult a professional tank-
cleaning contractor about having your fuel tank
pumped out and cleaned.
Dispose of the test sample following all state and fed-
eral regulations.
Verify that the contractor is fully licensed and that he
can dispose of the contaminated gasoline following all
state and federal regulations.

WARNING
Do not allow any liquid gasoline to enter the
boat or accumulate in the bilge. Liquid gasoline
is a fire and explosion hazard. Gasoline vapor
is extremely flammable and highly explosive
under certain conditions.
