Metering Pump Priming
If air entered the system due to the fluid tank(s) running dry during
system operation, it may require several cycles of the windshield/
priming pump to prime the metering pumps.
In the event that the metering pumps cannot prime themselves, the
windshield/priming pump may be cycled, 3s ON, 3s OFF, to draw fluid
from the tank to prime the metering pump manifolds and to remove
any entrapped air between the metering pumps and the fluid tank(s).
