Parts Used
Model P2800 Ryobi chem sprayer. removed all screws from the housing. Removed old pump and motor assembly. Installed new assembly and soldered the motor leads. It was difficult to disconnect the pump hoses as they needed to be heated with a heat gun. I would suggest buying two new connector hoses as you might tear the old ones. I had a small tear but the clamp cover it.

Parts Used
I Removed all the screws holding the two case halves together then removed the screws holding pump to one case half then removed hose clamps from pump hoses.
Then used solder iron to unsolder the two wires from the old pump motor. I installed new pump and connector with hoses and clamps.
I soldered the two wires back to the new pump motor. I screwed new pump assembly to one case half. I screwed the two case halves back together and that was it. It works great.
