First of all, Welcome to Oldgas Jerry.
Heres a link to a low cost pump restoration.
http://www.oldgas.com/shoptalk/ubb/Forum4/HTML/001409.htmlIts not the kind of pump that you're working on, nor is it a "Museum" restoration. But read through it anyways. Hopefully, it will give you some idea of what it takes for a pump restoration. You can take this approach, improve upon it, or send it out and have somebody do it all for you.
As far as the colors, the best way to do that is, buy your decals and have the colors mixed to match. This way there will be no mismatch between the actual pump color codes, and a decal thats just a bit off.
Post lots of pics too....
