Figure 1. Coalescer and Separator Elements Removal
SERVICE (Figure 2)
1.
Clean the separator element (1) in clean fuel and gently wipe the entire screen surface with a soft cloth or very soft
bristle brush.
2.
Holding the separator element (1) by the end caps (2), visually inspect the entire surface for any nicks or cuts. If there are
any visible flaws, the separator element (1) should be replaced.
3.
Perform water test.
a.
Touching only the end cap (2), hold the separator element (1) at an angle and gradually pour water over the entire
surface. Do not spray the water and do not let it fall more than three inches before contacting the screen. The water
will bead and roll off the surface of a properly functioning separator element (1) (similar to a freshly waxed surface).
If any portion of the screen appears wetted (water has soaked into the pores of the screen and will not bead) the
separator element (1) has failed and must be cleaned again. Proceed to step 4.
b.
Rinse the separator (1) thoroughly in clean fuel to remove all traces of water.
c.
Stand the separator (1) on end and allow to air dry.
4.
Re-clean separator (1) using hot water and a soft cloth or very soft brush.
5.
Repeat water test (step 3). If separator (1) continues to fail, it must be replaced.
