Just wanted to spread the word on something that could happen to you ! I just finished a LS swap and i used a quality name brand, Quick-connect, Male for a couple weeks it worked great at the fuel rail port. With no warning it decide to pull apart during a hard pull. The dual 450 pumps in my tank had no issue flooding the engine compartment instantly with fuel .The coil packs were covered with fuel / dripping with fuel. I'm am so lucky the whole car didn't burn down, I'm lucky nothing happed . I'm defiantly getting fire extinguisher for all my cars. Maybe someone can learn from my extremely stupid mistake.
