TM 9--2350--292--20--10221 00--2FUEL/WATER SEPARATOR OPERATION TESTS -- CONTINUED0221 00Manual Drain Test--ContinuedNOTEBe careful not to disturb center filter element during test.Center filter element must be replaced if disturbed in anyway.It may be necessary to unseat sensor probes by tappingupward on edge of sensor retaining nut.5. Remove upper sensor probe (2) from fuel/water separator (1).6. Open and close bleed cap (10). Check to see if fluid level is above upper sensor probe (2) hole by noting leakagefrom upper sensor probe (2) hole when bleed cap (10) is opened.7. Remove upper sensor retaining nut (11) and install screw (12) into upper sensor probe (2) hole.NOTEIt may be necessary to remove screw (9) and move fuel/water separator prior to removing lower sensor probe. Ifscrew is removed, reinstall screw (9) after removingprobe.8. Remove lower sensor probe (3) from fuel/water separator (1).9. Remove lower sensor retaining nut (13) and install screw (14) into lower sensor probe (3) hole.10. If fuel did not leak from upper sensor probe (2) hole, remove screw (12) from upper sensor probe (2) hole andproceed to step 11. If fuel did leak from upper sensor probe (2) hole, proceed to step 14.Figure 29231219101111314
