97 z28 fuel line relocation help

I have a 97 Z28. I just put jet hot long tube headers with 3in pipes adn an x pipe. i want to run it dual all the way out the rear (its way to loud inside the car with it dumping underneath). my problem is the the fuel lines are in the way on the drivers side, so i will have to relocate them. Has any one done this? will it create any problems with pressure? any suggestion on how to do it the correct way?

You will probably see similar if not better gains and better sound from running a nice 3" catback (sungle back) than fabbing up duals, not to mention lack of ground clearance with duals.
