The generator fuel system features an in-line remote fuel
fi lter. It's job is to keep fi ne particles and water out of
the generator fuel injection system. Refer to the vendor
information for periodic maintenance schedules. Clean fuel
is the life line of diesel engine performance.
Notes-Element Replacement
Contamination level varies in fuels. As the fuel system
slowly plugs the element fuel fl ow to the engine becomes
increasingly restricted.
Replace the element every 500 hours, annually, or at the fi rst sign
of power loss or hard starting which ever comes fi rst.
Note: The generator uses a primary Racor 500 MA fi lter
which carries an element fi ltration rating of 10 microns.

To Drain & Reassemble 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 filter bowl
assembly to catch the contaminants.
3. If needed use a fl ashlight and observe the bottom of
the glass bowl. Remove drain plug at the bottom of
the fi lter bowl assembly (14). Besides trash look for
water which will settle in the bottom of the fi lter bowl
(19) since it is heavier than diesel fuel. It will appear
as a different color. Drain the contaminants into
the container. Close container and retain for proper
disposal. Replace the drain plug. In extremely humid
conditions, the fuel system may require daily checks
and draining of water.
To Prime Racor Water Separator Filter
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. Open the filter top by turning the T-handle
counterclockwise. Remove the lid. Make sure the
O-ring is in good condition.
3. Pour a container of fresh diesel fuel into the head
assembly until full.
4. Coat O-ring with diesel fuel and install it in the lid.
Place lid on head.
5. Coat T-handle O-ring with fresh diesel fuel.
6. Reinstall T-handle into lid being careful not to damage
T-handle O-ring.
7. Hand tighten T-handle by turning clockwise.
8. Open shut-off valve and start engine looking for any
system leaks.
Note: See earlier part of chapter for fi lter parts and the
troubleshooting chapter for more specifi c information on
fuel fi lter problems and solutions.
