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 fuel tanks, 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.
Use your fuel stripping pump to sample the gasoline
for evidence of moisture or particulate contamination.
Adjust the boat angle so that the lowest portion of the
fuel tank is below the sounding hole. If possible, let
the gasoline “rest” for 30 minutes before sampling.
Pump the sample gasoline into a clean container and
inspect for moisture or particulate contamination. Dis-
pose of the test sample following all state and federal
regulations.
Refer to Fuel Stripping Pump in this section for
detailed information about this service procedure.
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.
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.
