Engine bay detail

I say it'll look good either way. If the top tank didn't have those beads rolled into it, I'd say leave it alone. But since it does, if you do decide to paint it black, it'll look real close to stock. Also, if it was mine, I would throw that rubber fuel hose in the ditch and hard line from the pump to the carburetor. It'll look much neater. @Johnny Dart is the dude to try and emulate the engine bay of. That guy's cars are works of art. Maybe he'll post a picture and make you drool since I tagged him. lol
