“SEEING IS BELIEVING”®
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. This far exceeds the
performance of cellulose media.
When new, the fuel level in the filter will be very low with
minimal restriction
. As the filter is used, contaminants
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 main-
taining 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.
