Still working on my project K100. Took the fuel injectors off and sent them  to Mr. Injector to be refurbished. Which will include new o-rings. But the original fuel rail was quite rusted on the outside. Inside didn't look too bad I thought but I can't tell for sure. Any suggestions on how to clean the inside of a fuel rail. The outside I'm thinking to just clean off and repaint or possibly powder coat. I haven't done a powder coating job in a year or two. So that would be fun. Wink  But I'm not sure how to get to the inside surfaces and get ride of any gunk or rust. Of course just using solvents might be ok for gunk. But rust would be an issue. Suggestions invited.
Thanks
J.

Get the exterior stripped, then, you can go after the interior.

First, I would go after the inside with carb cleaner and/or acetone to get rid of any gummed up old fuel.  Give it a good soak for a couple days and then blow out the interior. 

Follow that with a soak for a couple days in white vinegar followed by a vinegar rinse of the inside to get rid of the rust.  That should get you a clean part ready to powder coat.

Sounds good and sensible. Will give it a go.
