I thought I would add a question to this thread so it would be easier for others to locate if they search about VY fuel rails as there appears to be limited info around.
I have a VY V6 NA ecotec and the return fuel line / hose from the fuel rail has cracked and is leaking, it has a quick connector on one end going back to the fuel tank and the other is permanently attached to the fuel regulator on the fuel rail. The only option appears to be to replace the entire fuel rail assembly at a considerable cost $300+ new from dealership or secondhand (unknown condition of line / hose, who knows how long that would last due to age).
Another consideration I was thinking about was I'm forced to have to replace the fuel rail regardless as the hose on the existing rail cannot be swapped out, so if there is an earlier version of the fuel rail on older model engines that have replaceable hoses I would be better off trying to source one so if one lets go in the future it won't be such a saga. I'm hoping that someone may be able to shed some light on this whole topic and what options (if any) are available. Thanks in advance to anyone with further info.
