have you tried sucking on the hose feeding the water to the pump to make sure you dont have a restriction and at the same time the hose gets primed?

I have never used mine on my '69. Don't know if it works, or not. Not sure I would turn it on on a dirty windshield. No disrespect intended, that is just me.

when you say the front of the pump was replaced, you are referring to the piece with the small round oneway valves? Have you tried a small container with water and insert a short piece of hose from the pump intake to the container?

Try disassembling the front again, use vasoline or wheel bearing grease and put some on the o-rings and in the piston bore, see if that makes a difference.

OK , I tried the old face plate with new o rings, and now getting some water, might be the way the rubber check value is in the new plate?
Well thanks again, Back to fixen something I might not use, But sometimes it is the chase, AND there sure are a lot of moving parts in these Great cars, amazing it works at all.
