I have a custom dual feed fuel rail here. I took out the inner tube, installed 3/8'' barbed fittings on both ends soldered in and then JB welded around it to ensure no leaks. The stock inlet is a perfect fit for a 7mm bolt so I tapped it and JB welded it in to seal it off. The best part is it uses a stock fuel pressure regulator mounting provisions, nothing changed there.
Should flow tons more than a stock 1 piece rail, the inner tube takes up almost 1/2 the volume inside the rail. Plus the dual feed means there's no number 1 cylinder fuel starvation above 300 WHP. All you need is a 3/8'' brass ''T'' or a "Y'' for your fuel feed line.
