I too have been dealing with the routing of a fuel line, and I am waiting for my fitting to come in the mail. I have been using Earls' products, which are under the control of Holley. They make many many AN adapters for just about any combination you want to create. You can purchase these parts on Summit's website as well, they seem to be a quality product to me.
I use the Earls part. If memory serves the Russel is female only while Earls offers male as well. The advantage to using a male adapter is that a standard female hose end, which is easier to align, can be used.
