ok so i'm still working on my first EFI motor and i put bigger fuel rails on, but have come across a problem now. the stock fuel lines have the cuppler fittings right? well the after market rails dont have the same fittings. i'm guessing that i'm supposed to switch the fuel lines over to like a braided steel line or something similar. what do i do?

You are going to swap over to the braided steel lines i believe. Normally, though when people swap the rails they are putting all new fuel lines and fuel system. So this isn't normally a problem.. How much horse are you running, i ask because the stock rails are good for about 400 horse or 350 horse, and usually by then you need a new fuel system to support the engine as well.

You can get an adapter from the stock hardlines to an -8AN fitting from Summit. That way you don't have to run new hard lines, just the lines in the engine bay.
Summit part numbers:
RUS-640870 - return line fitting
RUS-640880 - feed line fitting
