I have a fuel pump marked AC 855220 that I believe was used on a 1931 Chevrolet. The exterior looks to be in good condition, but the inside looks like it has some oxidation. I would like to rebuild it and use it as a spare "just in case". I would like to know the best way to remove the oxidation and is the housing plated or conversion coated (anodized) to prevent future corrosion (hopefully it will be sitting on a shelf for a bit).
Thanks in advance.

My favorite way to clean a fuel pump casting is by blasting with nut hulls. This is crushed pecan or walnut hulls. It restores the original look of the casting without the telltale appearance of glass bead or other abrasive blasting. I have used nut hulls to blast many aluminum and white metal parts.
Obviously this requires access to a blast cabinet and is not possible for everyone.
I have heard of boiling carburetor parts to remove deposits and obstructions. If it works for carbs, it should work on your pump.
Once you get it clean, I don't think you will have to worry about the finish staying good in long term storage.
Good Luck.
