A fuel filter restricts the dirt & debris from entering the engine chamber. The fuel filter consists of various parts that are assigned special tasks. Like the base plate provides the installation interface & holds the pressure. The center tube supports filtration. See the following slideshow to know about the different parts of a fuel filter.

1. Do You Know the
Different Parts Of A
Fuel Filter?

2. A fuel filter prevents
contaminants from reaching
the engine.

3. The fuel filter is installed
in a fuel system to screen
out dirt & debris.

4. A typical fuel filter consists of
the following components.

5. Base Plate

6. This is a plate at the end
of the filter housing where
device mates with the
mounting assembly.

7. The base plate provides the
installation interface and hold in
the pressure inside the filter.

8. End Cap

9. The cap is a supporting
structure that holds the
filter media in place.

10. Attached to the filtration
media using adhesive, the end
cap also prevents leaks.

11. Center Tube

12. The center tube supports
the filtration and prevents
it from collapsing inwards.

13. Other than being a structural
component, the tube acts as the
outlet for filtered fuel.

14. Filter Media

15. This part is the membrane
that traps particles or water
and other particulates or
precipitates.

16. A filter media is usually pleated to
increase the surface area on
which filtration takes place.

17. Compression Spring

18. This spring provides
compression force.

19. It holds the internal
components in place under
varying differential pressures.

20. Drain Valve

21. When present in a fuel filter,
the drain valve provides a
means for fuel to bypass the
filter media.

22. It allows the fuel from the
tank and straight to the
engine unfiltered.

23. Water Sensor

24. A fuel filter water sensor is
usually fitted in the filters that
remove water from fuel.

25. When the water from fuel reaches
a critical level, the sensor sends a
signal to the dashboard light.

26. Canister

27. This is the housing that
protects the internal
components of the fuel filter.

28. Made from steel, the canister
contains the pressure inside the
filter and prevents it from bursting.
