Here are the parts I anodized last night. Came out pretty well.

As I was about to reassemble the check valve, I noticed some burrs on the inside of the check component. Not good...I'd hate to have one of these little guys break off and clog my fuel injector. Actually that wouldn't really happen...any debris from here would eventually get caught in the fuel filter.

After some judicious work with an X-acto knife, I had a neat little pile of burrs. Glad I noticed this.
