ok the 05 maxdaspeeds have a returnless fuel system now would it be te best to just do a braided line off a high flow fuel pump or swap parts over to make it a return style...thnx for all help in advance..
also i will be posting pics of the whole build when i am finished in the build thread

 

your doing a mazdaspeed swap into an early car correct, if so reuse fuel rail and lines, upgrade fuel pump and profit, use mazdaspeed injectors as well.

 

You reuse the Mazdaspeed fuel rail but add a 1 to 1 (stock type) regulator to the line and reuse the factory return line back to the tank if using aftermarket ECU. You use a fixed value regulator if reusing the Mazdaspeed ECU.
