Can anyone tell me if the fuel rails have changed on a 2019 mustang gt from previous years. I’m having problems with the fuel rail adapter from nx express. I can’t tighten up the 90degree fitting enough for it to not leak. If I snug it up by hand then the threads push through to inside the adapter and then I cannot slide it onto my fuel rail. For me to be able to slide it on fuel rail then the 90 fitting has to be super loose. Anything I’m doing wrong
