When you say "AN", do you mean Aeroquip style braided hose anf fittings? If so, yes, the braided line is available with the SAE flares and is reusable for the engine swap. e.g.
Aeroquip hose and fittings

I don't know, but If the 292 needs a longer line than the 250, be careful not to cut it too short!
