I'm trying to rebuild my k181 vacuum/pulse fuel pump. After some some searching, it's appears to be well-known that the rebuild kits have been NLA for quite some time.
What do I need to get to make a new membrane? Where would I look for it? Maybe that will translate to something in Canada.
Folks at Benson's sold me some rubber gasket material, but when I tried to flex it it tore. That won't work. Also, because it's for gas, rubber from an inner tube won't work.
