Are you asking about AN fuel line fittings?  If so, best practice is that mating fittings should be the same material - aluminum to aluminum, stainless to stainless.  Sometimes, this is not possible - I once had a stainless gascolator fitting/firewall mount that had mating aluminum AN fittings and never had a problem with corrosion or leaks.

Personally, I prefer quality aluminum fuel fittings where possible (I mostly use Earl's from ANplumbing.com).  They're marginally lighter than stainless and have never had one leak!

+1 for earls, I used their products for my entire fuel system and brake lines, they go together very easy and have been leak free so far.

I've used Jegs -- quick service (probably similar for most of the big, online speed-shops, Speedway Motors, etc...)
