Danger! When servicing gasoline
fuel systems, extreme care must
be exercised to avoid potential
fire hazards. Do not smoke or
permit open flames near fuel
during servicing procedures.

becomes restricted as filter
slowly plugs with contaminants,
resulting in noticeable power loss

or when there is a noticeable
power loss, whichever comes
first. Change filter as soon as
possible. Note: always carry extra
replacement filters as one tankful
of excessively contaminated fuel
can plug a filter.
