Modified my sr20det OEM fuel Rail. Please do not attempt this unless your willing to risk it. Must be a competent welder to do this task. I believe this fuel rail was brazed together in sections. There is some sort of copper/brazing material that must be removed before attempting to weld otherwise you won't get a solid weld with the correct metallurgy. I had it cracked initially because the brazing material got mixed in my weld so I had to remove it completely.
