Item corresponded exactly to the description. I already installed it. The threaded ends of the hose connections are securely sealed with Teflon tape. The fuel system was absolutely tight after bleeding.
Well, the seal is poor. Of course you can seal it with Teflon and other stuff. You won't find a flange for a copper ring here. If I buy something new I don't want to have to tinker with it, otherwise I can repair the old one right away.
A high level of accuracy is particularly important in the fuel line. This important component is imprecise and unclean. The threads also have burrs. Apparently the brand lacks quality control, as I have had the same experiences with other items (e.g. fuel hose coupling).
