Sprayer Rebuilding 3 Point 100 gallon sprayer ... Help!

[blueriver]

I have never owned a sprayer, my neighbor gave me a 3 point 100 gallon sprayer. Needs work. The tank is good fiberglass and fairly clean. The pump is gone, the hoses are bad, the regulator is stuck and the pressure gauge is bad. The tank has a top fill hole and two holes on the bottom. Now I need to know the proper layout. I assume one of the bottom holes gets a filter then the line runs to the new PTO pump, then back out to the second hole for recirculation and then ????. Does anyone have a diagram or layout? Any help would be appreciated.

Don't forget when looking at the chemical manufactors' recommendations, to check gallons of spray mixture required per acre for good coverage. This relates to tips size, nozzle spacing, boom width and tractor speed. Without getting the proper amount of liquid down to cover the plants or get the material into the soil depending on what you're using your effort and costs of materails could be wasted. I think TEE JET, a nozzle manufacturer, has instructions for sprayer calibration.
