See when NOT to change the fuel filter .
See the condition of the fuel . Seeing what collects on the filter media or what’s happening inside the clear cover can help
diagnose many fuel and mechanical conditions .
“Filter on Top” configuration . Water and debris removed from the fuel falls to the lower chamber and stays away from the
filter media resulting in longer filter life .
Built in protection when priming the fuel filter . Unfiltered fuel is kept on the “dirty” side of the filter media during priming
ensuring only clean fuel reaches the engine .
Patented media . The “Best in Class” StrataPore™ media removes 98% of free and emulsified water over the life of the filter .
This far exceeds the performance of cellulose media .
“SEEING IS BELIEVING”

When new, the fuel level in the filter will be very low
with minimal restriction . As the filter is used, contami-
nants collect on the filter from the bottom up . Fuel rises
on the filter indicating remaining filter life .
Fuel level increases in clear cover . As contaminants
collect on the filter, the fuel rises to a non-contaminated
section of the filter, providing optimal filtration while
maintaining lowest restriction .
Fuel level at filter wrap level . Even though the fuel level
is now more than half of the filter element, the fuel is still
flowing through clean media at minimal restriction levels .
The filter still has significant life remaining .
The filter element is now completely covered by fuel .
At this point, all of the media’s surface area is utilized .
Restriction is increasing and the filter element should be
changed at the next scheduled maintenance interval .
