WARNING
Fluid circulated through the fuel/water separator
to heat the fuel may be diesel fuel returned from
the engine, or engine coolant. Drain the fuel/water
separator only when the engine and fluids have
cooled. Draining it when the engine is hot could
cause severe personal injury due to scalding.
If returning fuel is released into the atmosphere,
its vapors can ignite in the presence of any igni-
tion source. Do not expose the fuel to, or work
with the fuel system near, open flame or intense
heat. To do so could cause fire, possibly resulting
in serious personal injury or property damage.
The filter element should be changed only when the
fuel level has reached the top of the filter element.
There is no significant restriction to fuel flow until the
element is completely clogged.
1. Shut down the engine, apply the parking brake,
and chock the tires.
2. Check the fuel level in the fuel filter. Replace the
fuel/water separator element
only when the filter
element is completely covered. If the fuel level
has reached the top of the filter element, follow
the procedure below to replace the element.
3. Put a clean receptacle under the fuel/water sepa-
rator and attach a piece of hose to the drain
valve, to direct fuel into the receptacle.
The drain valve has a 1/2-inch (12.7-mm) pipe;
use a hose with a 1/2-inch pipe thread to fit cor-
rectly.
4. Remove the vent cap, shown in Fig. 6 , Item 10,
and open the drain valve, shown in Fig. 6 , Item
1, to drain the fuel completely, then close the
drain valve.
5. Using a DAVCO Collar Wrench, shown in Fig. 4 ,
remove the clear cover and collar.
NOTE: Broken vent cap and collar warranty
claims will not be accepted if any tool other than
a DAVCO Collar Wrench is used for removal.
During installation, the vent cap is to be
hand-
tightened only , not tightened with a wrench.
Use part number 380134 on Fuel Pro 382 units.
6. Remove the filter, cover O-ring, and vent cap
O-ring. Dispose of them in an environmentally
acceptable manner. See
Fig. 6 .
7. Clean all threads and sealing surfaces very thor-
oughly. Even a small amount of dirt will prevent
the fuel/water separator from sealing, and an air
leak may result.
8. Install the grommet on the bottom of the new
filter.
