Yes, AN lines can be adapted to a mechanical fuel pump. That is the way mine is currently setup. I don't know exactly what fitting you'll need but it's probably a NPT to AN adapter or something like this http://www.summitracing.com/search/Product-Line/Summit-Racing-AN-to-NPT-Adapter-Fittings/. If you change over to braided line, you can route wherever you want and the AN end fittings are not that hard to install.
