Go to a good parts store with a Dorman or similar selection of brass fittings. Take both hoses with you. You are looking for a double male threaded fitting with that flare. Match the threads and flare on the original male - this end screws into the box. The other end should have male threads that your new hose attaches to. And are you sure the bends and fittings on the new one will fit? Pic looks like a very different hose.
