Are you able to tell us the brand of the water pump?
From what I can see it might be a Fynspray? If so there is some information on how to pull it apart and recondition it here. Scroll down past the first few sections until you get some photos. Sadly some of the earlier photos have been lost.
Let us know if that helps. Otherwise if your hand pump is some other brand, we may be able to find some insructions or posts that will help.
Hi Don, I think it's from the 1960s. It was pulled out of a very old van and I bought it. I have managed to pull it apart and the washer has almost disintegrated. It is identical to the one you referred to me to so that was very helpful. My only issue now is I have no idea where to source a washer from. But it's a great start! Thanks! Leesa
I can't open the link that DonR sent you, so don't know what he is showing you. If the part you are looking for is washer shaped with a lip on it, then they are called buckets. I bought mine on ebay. A pump supplies place or even a place like Reece Plumbing should also have them or be able to access them for you.
Did you use vernier calipers to measure the internal diameter of the housing? If its not exact,you'll suck air. Maybe also the hole is the wrong size. I bought one without a hole and drilled it to size myself. When you've got it working, you may still need a non-return valve in the line to the pump, so that the water stays in the pump for next time.

Hi Roehm3108, I had the internal diameter correct as I'm a silversmith and used my calipers. So after thinking about it, and re-reading your posts, I attacked the washer I had bought with a steak knife and amended it to fit. It works like a dream lol.
