Gas tank diaphragm assembly

[gunnarsedley]

I would like to either purchase one of these or a kit to rebuilt

The pin in those kits is too short. See the workaround in post #10 in the link below.

I have purchased the diaphragm from both of those vendors. They are the same K&L part. I reached out to K&L. No response. K&L appears to be the only game in town. I did that fix on my Eleven Special and it worked great. Be gentle. Maybe buy two.
