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 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 .
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 .
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 .
“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 .
