[AT] sprayer pump

[H. L. Staples]

Brad--The roller pumps are pretty cheap as pumps go and the rollers wear
pretty quick.  If it is a Hypro parts are readily available.  A pressure
regulating valve should be in the circuit from the pump to the control valve
with the discharge returning to the spray tank.
