Th e cloud point of fuel must be at least minus
10 degrees Fahrenheit below the lowest outside
temperature to prevent plugged fi lters due to
wax formation.
4.Asphaltenes. Th ese are components of
asphalt that are generally insoluble and are
generally present to some extent in all diesel fuel.
Th e black, tarry substances are hard and brittle,
and are made up of long molecules.
Fuel with a high percentage
of asphaltenes will drastically
shorten the life of a fuel fi lter.
5. Sediment and other
solids. Various tiny
materials oft en make their
way into fuel tanks and cause
problems. Most sediment can
be removed by settling or
fi ltration.
Fuel filters designed for
specific applications will
remove these harmful
contaminants before they
cause further system wear
and damage.
Warning Signs
of a Fuel System
Problem
Th ese are the most noticeable
indications that too many
contaminants are reaching the
fuel system, or that a fuel fi lter
needs to be changed:
Loss of power – A severely
dirty or clogged fuel system
can cause a vehicle to experience
a decrease in power and
acceleration.
Hesitation – Stuttering
and jerking produced by the
engine can occur when one or
more cylinders misfi re due to
damaged or underperforming
injectors.
Hard starts – Restrictions
in the fl ow of fuel through the
fuel system can cause a vehicle
to experience hard starting or
extended cranking.
Conclusion
While oft en not as top-ofmind
as oil and air fi lters,
fuel fi lters comprise a quarter
of the heavy duty fi ltration
market. Because of the severe
consequences contaminated
fuel can have on a vehicle’s
fuel system and engine,
it’s extremely important for
fl eets and service personnel
to understand the key benefi
ts of a properly maintained
fuel system, and how fuel
fi ltration contributes to fuel
system performance.
