I use a turkey baster to prime the system while the pump is pumping. Also, while the system is apart blow through all of the hoses and squirter nozzles with an air hose. Do not blow air through the pump, you could rupture the diaphram in the pump. (and blow backwards through the squirter nozzles) Oh, and don't forget to clean the small strainer screen inside the washer tank.

If you decide to go with the external pump there are instructions on here for wiring it to the original wiper/washer switch.....

I checked out post 95 on testing the pump and I would like to try the kit replacement. I see you mention the turkey baster to prime it with which I will do. Question though, is there a similar way to test the pump with the jumper wires while I have it on the bench vs in the truck?
