Priming the system
Make sure the air has been eliminated from the water
separator. Then unscrew the bleeder screw (5) a few
turns. Operate the priming pump (1). When fuel exits the
bleeder screw (5) without air bubbles, tighten the bleeder
screw.
Note
Some fuel systems make use of gravity to eliminate air
from the pre-filter. For such systems you must make sure
the fuel tank is full and that shut-off valves in the fuel line
are open.
There are various types of systems that can be mounted on the engine to purge air from the fuel
system.
Fuel System Primary Filter/Water Separator - Drain
WARNING
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.
To help prevent possible injury, turn the start switch off when changing fuel filters or
water separator elements. Clean up fuel spills immediately.
NOTICE
The water separator (3) is not a filter. The water separator separates water from the fuel. The engine
should never be allowed to run with the water separator more than half full. Engine damage may result.
1. Open drain (2). Catch the draining fluid in a suitable
container. Dispose of the drained fluid correctly.
