Default washer pump not working on 72

I have a remanufactured wiper motor, new washer pump, new wiper hoses, tubes, cap, filter - everything that would come into contact with the fluid - and I get no fluid. The switch is original but wipers work and there is an audible click when pushing in on the washer button. Took the cap off the washer pump and the spring action lever goes up and down so I'm guessing that means it's properly connected to the motor.

What am I missing?

And don't say the fluid.

I went through this with my one. In my case the plunger piston rubber seal ring had shrunk, so the piston was traveling correctly but was not sucking any fluid. The other thing to check is that the little one way valves don't have any crud under them. I gave up on mine but may re-visit it one day.

Did you prime the pump? In many instances the pump won't pick up it's prime so the easiest way to do this is pull the feed hose from the pump... insert a 2' long vacuum hose on it. Take a large drink of water and hold it in your mouth and then force it into the pump via the vacuum line.. you'll be amazed..

Try that.. post back...

I used this method as described by Wilcox on my '68 and suprisingly after priming it worked. You push the button and it pumps 3 squirts.
Amazing.

Finally got around to it. Blew the water in, and it leaked out the bottom of the pump and onto the floor. Took the pump off and went over to the sink. Blowing in the center hole sends nothing out of the side outlets. It just gushes out of the bottom of the reservoir. Tried that with my old washer pump and it shot water out of one outlet but not the other. It also leaked.

I had to get my washer pump working a few years ago because the guy at the inspection station was being a pain in the a$$. I figured I wasn't going to find a double lip-seal seal anywhere local, so I improvised. I went to the hardware store and bought 2 O-rings. One of them just about fills the original slot and the other one makes a fairly tight fit in the washer bore.

I crossed my fingers, ran the washer and water squirted out the nozzles so I was able to get an inspection sticker. It's still working 4 years later.
