Oil Pump Priming
This priming procedure must be
performed whenever the oil hose
connection between the oil tank
and pump inlet has been
disconnected.
1. Clamp or pinch off the vent
line (1) approximately 2I
from the oil tank (2),
between the end of the oil
tank vent fitting and the vent
line's pressure relief slit (3).
2. Run the engine for 10-20
seconds.
3. Remove the vent line clamp.
If the line is bled properly,
you should hear a rush of air,
indicating that the line is
properly primed and ready for
operation. If you do not hear
air, the line has not bled, and
you'll need to repeat the
priming procedure.
