Oil Pump Priming Procedure

NOTE: 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 vent line approximately 2" from oil
tank to avoid the end of oil tank vent fitting, and before the
vent line's pressure relief slit.
2. Run engine for 10-20 seconds.
3. Remove the vent line (A) clamp. The oil pump will now
be properly primed and ready for field operation.
NOTE: If the system is primed properly you should
hear some air release. If you do not, the system has
not primed. Repeat the process if necessary.
