[AT] sprayer pump

[charlie hill]

Brad go to this page and you can find about any kind of ag sprayer part you 
need.  It should give you some ideas about what you need to do.  You need a 
bypass line of some sort even if it's manual.  You can always run the 
presure line to the spray header with a Tee in the presure line.  Valve the 
other leg of the tee and run a line from that valve back to the tank.  That 
way you can use the bypass for an agitator line if your spray solution needs 
to be mixed or agitated.
