- Honda Water Pump WP20X, WP30X Owner's Manual

OPERATION
DISCHARGE HOSE INSTALLATION
Use a commercially available
hose and hose connector,
and
clamp provided with the pump.
It is best to use a short, large-dia-
meter hose, because that
will
reduce fluid friction and improve
pump output.
A long or small-
diameter hose
will increase fluid
friction and reduce pump output.
DISCHARGE HOSE
Tighten the hose clamp securely I
to prevent the discharge hose HOSE CLAMP
from disconnecting under high
pressure.
PRIMING THE PUMP
Before starting the engine, remove the filler cap from the pump
chamber, and completely fill the pump chamber with water. Reinstall
the filler cap, and tighten
it securely.'
m
Operating the pump dry will destroy the pump seal. If the pump has
been operated dry, stop the engine immediately, and allow the pump
to
cool before priming.
