I'm annoyed - spent over an hour sanding and lapping the mating surfaces on my mechanical fuel pump. But noone's got a rebuild kit for it when I go looking. I can buy a new pump for less than the cost of importing a rebuild kit.

On the upside, it looks pretty.

that was about 600 grit, about half-done

Had the opposite side and the block mounting face too

they were all wavey - seems the metal has "pulled" over the years.
