Does anybody know of a -6an flare to a compression fitting that is compatible with the stock ls1 fuel distribution manifold? I found one but the threads weren't compatible with the factory 20 threads per inch. Any help would be appreciated.

 

-6an to fuel rail input? I used The Russel EFI fitting.
