PTO PUMP maintenance (Sprayer)

[pharmvet]

Both my Wylie manual and coffee shop informants tell me to run some machine oil through my sprayer pump after use to keep corrosion to a minimum. I tried to remove the intake and outlet hoses today by loosening the hose clamps but they were a PITA to remove. In fact, I did not get them removed. This has me thinking. Is there any such brass valve that could be used here between the intake hose and pump that might have a port that could be opened to introduce machine oil into? Maybe then there could be another on the outlet side between the pump and hose that could be opened to allow the oil to drain out without going on down the line. If there is any such beast, please tell me what it called and where to get it. If you guys have come up with any other easy ways to run oil through the pump please let me know. thanks

A hair drier to warm and expand the hose is the best way. adding another fitting will increase the possiibility of sucking air and ruining the pump.

I installed banjo style fittings on both ends of my pump. That way I can disconnect the hoses from the pump, fill with anti-freeze, and bring in the garage for the winter. Banjo fittings also have caps available to keep contaminates out.
