Hey y'all, I just had a quick question... I had to replace a cracked intake manifold on my 99 GT. It's dont and back together, havent started it yet, as I need a new alternator bracket... but my question is, the fuel rail screws... the factory maniflold had metal inserts and screws holding the fuel rail down and the injectors in place... the new plastic manifold has self tapping screws... all is well except for one of the screws doesn't tighten, just keeps turning... it's sort of snug... but not tight as I woudl like it to be considering it's fuel... the rail feels solid and doesn't move, I'm just concerned about high fuel pressure and a fuel leak? as in the vibration of the engine working it loose? should I be concerned? thanks!
