Changing Element
The element due to contaminated fuel needs to be
changed periodically. Be sure to close the generator
fuel tank valve located in the engine room berth before
changing the element
Signs of necessary element replacement may be power
loss, hard starting or large levels of contaminants/water
in the element collection bowl when drained.
To replace the element fi rst remove the old one by turning
it in a counterclockwise direction by hand. Be sure to
have a pan in place to catch any dripping fuel. Coat the
new element and O ring with fresh diesel fuel and then
thread the element clockwise by hand until snug. Do not
use any tools.
Loosen the vent plug. Turn the primer valve
counterclockwise until fully open. Turn on the generator
fuel tank valve located under the master state room berth.
Hand operate the primer valve up and down until the
element is full as seen by fuel purging at the drain plug.
Bleed the system as needed. Close the vent plug snugly.
Close the primer valve by turning the valve clockwise
until tight.
Start the engine and check for fuel or air leaks.
Bleeding System
Periodically air may need to be bled from the generator
fuel system. Basically as stated above loosen vent plug and
the hand operated fuel primer valve. Pump the primer
until a solid stream of fuel comes out of the plug verses
some fuel and some air bubbles. Tighten all components
until snug.
Draining Collection Bowl
Since water is heavier than fuel it will settle in the
collection bowl at the bottom of the element. Th e vendor
recommends inspecting/draining the collection bowl
daily. To check/drain the element loosen the drain plug on
the bottom of the collection bowl. Use an environmentally
safe container to catch any contaminated fuel. Dispose of
according to local, or state regulations. Close the drain
snugly when fi nished to prevent any fuel leakage.
Note: Water in diesel fuel will gather at the bottom of
a container since it is heavier than diesel fuel and will
appear as a diff erent color and consistency.
