I would likely get a used fuel rail. There is not a lot of demand for them, so it should be reasonable at a pic-your-part or a boneyard. If you cannot find one, cutting off the damaged connector/fitting and using a compression fitting combination to connect to the fuel line is one alternative. I would likely go with a used rail as you do NOT want fuel under pressure to be sprayed around under your hood. Unless you have good insurance. And a fireproof suit. And a breathing apparatus. And can run. And...
Of course, being where you are, your selection may be less than desirable. I don't know if any other fuel rail will fit. I would check car dash part dot com for the part as it will likely show other models that use the same part.

Thanks for the help, i replaced the fuel rail with the one off my old motor and she started right up no more fuel leak. Now im getting a terrible shake at idle but as soon as i apply the gas it stops. Ive done some research and it seems like it could be a stuck open fuel injector, my cat was blood red after 2 minutes of idling and was putting out some white smoke. It was the first start up with my new motor and its not throwing any codes does this sound like an injector issue to you?

Yes, a cat fed a lot of raw fuel can turn cherry red. That is not good for the converter.
I would take the fuel rail off, and pull the injectors. You could narrow down which cylinder by disconnecting the ignition(COP primary) one at a time, and whichever didn't change when you pulled the wire should be the one being flooded.
Once determined, you can have it serviced or get a used or new replacement. If used, be sure you don't get a 'flex fuel' unless you have that option. They are set up to flow more using E85, and must really 'trim back' when using E0-E10(more normal gasoline).
