In other applications, the run-of-the-mill external surge can like the radium is the go-to solution. In cars with return venturi's, theres a little more thought to put into it.

Which is why you could use a quality can like the radium one and not worry about putting it under 10-20 psi of pressure(at worst), then mount it up front or under the car, you also don't have to worry about getting 40-50 lacerations trying to run 10 feet of line across the inside of the factory tank and bending baffles out of the way by hand. Gas hurts like hell when you get it in a cut.
A 255lph in the factory unit with the regulator replaced with a straight through fitting, with a 90 degree bulkhead on the top to feed the venturii's with no regulator to restrict it and then do an easy return setup up front like ur stage 0 or just a set of rails with new lines, return and supply from the factory pump to the radium unit, and then from the radium's supply and regulator to the rails or line adapter. it isn't hard at all and like i said if your worried about it just mount it under the car or in the front like most external surge cans are anyway
