Emergency Filter Replacement, Davco

m2 dm 13.05.001

If the filter cover on the Davco fuel/water separator is broken, it will not be possible to operate the vehicle. A standard spin-on filter will correct this problem.

Refer to the Davco web site for additional information, www.davco.com.

To replace the filter on all Davco fuel/water separators, follow these procedures:

  1. Drain the fuel until it is below the level of the collar. See Fig. for the model 382 fuel/water separator.

    1. Filter Collar

    2. Filter Vent

    3. Filter Vent Seal

    4. Filter Cover

    5. Filter Cover Seal

    6. Spring

    7. Filter Element

    8. Threaded Stud

    9. Fuel Port

    10. Drain

    11. Bottom Plate Collar

  2. Remove the filter vent and vent seal.

    3. Note: The filter vent and vent seal are not needed in the emergency replacement. They should be retained for later installation at the time when the filter cover is replaced.

  3. Using a DAVCO collar wrench, shown in Fig., remove the clear cover and collar.

    4. Note: Broken vent cap and collar warranty claims will not be accepted if any tool other than a DAVCO collar wrench, p/n 380134 or 382002, is used for removal. During installation, the vent cap is to be hand-tightened only , not tightened with a wrench.

  4. Remove the filter cover, filter cover seal and spring. Retain them for later assembly.
  5. Remove the filter element and dispose of it properly.

    6. Note:  Remove the rubber grommet from the stud.

  6. Install the standard engine spin-on filter (included in the emergency kit) on the threaded stud.
  7. Install the filter cover, filter cover seal, and spring, as removed.
  8. Install the filter collar over the filter cover. Simultaneously apply downward pressure to the top of the clear cover until it is seated on the body of the lower housing and hand tighten the collar until it no longer spins freely. Using the collar wrench, tighten the cover 18 lbf·ft (24 N·m). This is equivalent to rotating the collar clockwise two or three additional ribs, depending on the specific filter model.
  9. Start the engine and run it at increased rpm for one minute to purge air from the fuel lines.
