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 dont mind replacing with a kit, but is it too difficult to test what I have now while its not installed on the truck? Currently the wiring harness hasnt been installed yet.

I watched this video on the replacement but this one is a 67 chevy van but its installed on the van while testing. The intro is creepy, but past that its informative.
