Pulled fuel pump head and broke a bolt

[Meanwhile]

I got my pump back. I had duct tape covering the bores for the tappets which was basically gone when I got it back. Luckily the tappets were still in there which I packed paper towels into them to keep stuff out. I went around everything I could think of with a magnet and got as much metal shavings as possible. I hope I got them all. After pulling the tappets out, I wiped all the oil off the bores and took a good look. There is wear on the walls. The tappet wear I can feel with a fingernail. Here’s a few close ups of the cylinder walls. Should I put it back together or should I get a new pump?
