Dave, Not sure I would attempt making crisp creases in the panel. I don't think they were that defined from the factory. If I was restoring this pump, I'd just go with what you have. I think the bends as is will be fine and distinctive for the project. You can do a lot of defining when you do the sanding of the primer. Good luck. This thing is going to be killer. What is the gas brand you are doing?
