to assure an adequate supply of clean, dry fuel to the engine. It is recommended that the filter
be inspected after the first 25 hours of use and then serviced as needed. Follow the engine or
filter manufacturer’s instructions for servicing or replacing the fuel filter.
Notice: Clean fuel is especially important in fuel injected engines and the engine
manufacturer's recommendations for fuel filter maintenance must be followed
exactly.
3.3 Diesel Engine Fuel System
The diesel fuel system works much like the gas system. The main difference is the diesel
system is not equipped with an anti-siphon valve and there is a fuel return line for the engine.
There is also an additional fuel valve located near the fuel filter that is used to shut off the fuel
when the filters require service or when replacing the filter element.
Proper diesel engine operation requires a good supply of clean, dry diesel fuel. Improper
marina fuel storage techniques, limited boat usage, etc. can cause the fuel to become
contaminated. Periodically, it may be necessary to siphon accumulating
water and contaminated fuel from the bottom of the fuel tank. If the fuel system on your boat
becomes contaminated, contact your dealer or Pursuit Customer Relations for assistance.
Algae can grow in the accumulated water in diesel fuel tanks. This condition is most prevalent
in warm climates. Periodically adding a high
quality diesel fuel additive containing an algae-
cide may be required to control algae in your
boating area. Please contact your dealer or
engine manufacturer for additional information
regarding fuels and additives.
IMPORTANT: Do not allow the boat to sit
unused for an extended pe-
riod with the fuel tank less
than full. Changes in tem-
perature and weather
conditions can cause con-
densation in fuel tanks that
are less than 3/4 full.
Diesel Fuel Filter
The diesel fuel filters are installed in the engine compartment. A shut-off valve is located at
