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 (2). 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 (2) and will not bead) the separator element (1) has failed and must be cleaned again.
Proceed to step 4.
Pass (Water Beads)
Fail (Water Does Not Bead)
Figure 4-4. Separator Element Cleaning
(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.
