kravdraa asked how I fixed my primer pump so here goes.

First you need to grind the crimped flange off of the formed sheetmetal cover. Then you will need to remove the two flapper valves and clean and or straighten them so they can seal to the aluminum casting.

Then, you will need to reassemble this thing. This will require a clamping method. I made some aluminum rings which work very well and can be undone whenever the pump might need service again. Making the rings will require a lathe and a drill press. Not much else. Might be able to do it with hand tools.

I am attaching three photos to show what I am talking about.

Here is the finished filter.



Here are the rings.



And here is a sketch of the rings to help anyone make them.



Hope this fixes a ton of bad pumps..

This is a great repair - very impressive <img src="/forums/images/graemlins/kewl.gif" alt="" />. It never ceases to amaze me to see the quality of work out there in folk's garages. I see stuff like this and I feel like a hack.

I do have an Atlas 6" lathe. Even though I purchased a new pump from Jerry, I may try this to fix my old one just to have a spare.
