Vacuum manifold or valve

[55 cadi]

And I have found that ace hardware has rivets that match in size, only thing is to be able to crimp down, I used a ball bearing larger than the end and used vise grips to squeeze the ball to mushroom the end and worked great.
The second picture: right rivet mushroomed, left rivet not done yet.

I have learned from rebuilding these and washer pumps to not over tighten the rivets!  The gaskets actually need a bit of give or the units will not work properly.

Ok,

But my original didn't have any play in it, also wouldn't that cause an air leak?

[Walter Youshock]

Yes, it could.  Over tightening can also cut into the gasket thereby causing a leak.  These are not gaskets!!!  They act as valves.  They need a bit of play to get seated properly.  It would be like trying to sleep on a sheet of cotton or a sheet of steel.  It needs some give to work properly.

This sounds like a topic for an excellent and useful article for the Self-Starter. I suspect that many owners, who might be "internet-challenged", would benefit from this knowledge. Roger, would you consider submitting it (with photos) to Steve Stewart?

Jim, I wrote that article. Unfortunately, it was never published; I got once a notice that too many things are on the waiting line; maybe it will be published in the year 2095!
