I had asked what people are using for washer bottle/jar/tank mounted pump and did not get a lot of replies or answers. I tried one of the non tank mounted pumps and it was noisy and leaked.
I had purchased a push into a rubber grommet type and was not impressed. Installing it into a reproduction tank (thinner than OEM) looked hack with the amount of silicone caulking/sealant I ended up using. I bought an OEM used tank and a couple of NOS (in case I wanted to return to original)
I also purchased an AC Delco pump that screwed into a tank mounted grommet but did not come with a nut or filter. Member Greasy Harley informed me the Anco 63-01 pump comes with the filter nut.
Here is what I ended up with and I believe it will work (not tested, too cold and I painted the bracket).
And here is looking inside you can see the filter nut.
