Can you modify a 03 cobras stock fuel rails to run a return style fuel system? If so how?

You have to run deadhead (regulator and return before rails) to use the factory rails.

Many of us have done this well into the 700s.

So you'll have a line coming off the regulator with wye block. To the back of the rails. Then a crossover in front? Do will 8an line hook up to both rails in the back?

The car had a crossover from the factory. You can only feed one rail
Via the stock location with factory rails.

Fuel feed from pumps to reg before rails.

Reg feed line goes to stock hookup on rails.

Return runs from reg back tank.

Thanks man, it's really appreciated.

Sure thing.

Check out the distillery thread.

Every question about return and E85 has been addressed.

There’s a few vendors on here that can line you out with a good return setup and save you some coin.
