DIESEL FUEL SYSTEM FILTERS
Regal yachts feature a primary and secondary fuel fi lter
system to provide maximum engine protection. Both en-
gines offer an in-line 10 micron Racor water separator
fi lter which is the fi rst line of defense. In addition, Volvo
provides a secondary fi lter mounted on the engine for
enhanced protection from water, dirt and "algae" micro
organisms/clusters.

To Drain Racor Water Separator Filter
The Racor diesel fuel fi lter should be drained frequently and
checked for water and other contaminants as needed:
1.
Place fi lter fuel valve in the "off " position which is
perpendicular (90) degrees to the fuel lines. Failure
to turn valve off may allow a continuous fl ow of fuel
due to siphoning.
2.
Place a suitable container below the fi lter bowl assembly
to catch the contaminants.
3.
Remove drain plug at the bottom of the fi lter bowl
assembly. Drain the contaminants. Replace the drain
plug.
4.
Replace the drain plug. See section on "priming.

Examine the diesel fuel in the drain container. Water is
heavier than diesel fuel and will be noticed as a different
color on the bottom. If water is present tilt the pan and
any water will move on the bottom. In extremely humid
conditions, the fuel system may require daily checks and
draining of water.

To Prime Racor Water Separator Filter
1.
Loosen the air vent plug on the top right side of the
fuel fi lter.
2.
Operate the primer valve until diesel fuel emerges from
the air vent plug free of air. In some cases, multiple
pumping is required depending on the amount of air
in the fuel system. Also, it is a good idea to prime the
engine secondary fi lter as air could be trapped in the
lines.
3.
Close the air vent plug and tighten securely.
4.
Start the engine and check for leaks. If the engine is
diffi cult to start or is rough running check to see that
all connections are tight and there are no kinked fuel
lines.
