I have a tell tale blue dye trail around my oil fill door and on the underside of the cowling. I cannot figure out where it is coming from. Yesterday I removed the line from the divider, capped it, fuel valve on, boost pump on, full rich and full throttle, not a drop leaking anywhere. There was fuel if it was going to leak at all but it did not. I cant attach the divider without flooding the engine (obviously), so not sure about capping all the injector lines at the injector or maybe the divider. I attached some photos of the stain. No blue stain seems to exist anywhere else on the engine. Are leaks from divider onward common? Any advice on best way to track this down?

btw: I really hate that blue dye as it does not seem possible to remove the stain without very harsh chemicals.
