Jim,
Sounds like you are on the right track. I never took one apart, I found
mine at Carlisle this year. It is out of a '4, but looks OK and it works
fine. I know a TR guy with lots of washer pumps from various '3's he has
parted in the past, and none of them work!
All I can add is there is no check valve exernal to the pump, and my pump
will squirt water on the first time you hit the plunger. I would guess
there has to be some sort of check valve in there.
It looks like you will be taking yours apart to see if you can fix it. If
you need parts from some other broken ones, I'd bet I could get my buddy to
sell a few broken pumps real cheap.
Good luck.
