I almost have everything together for my custom intake. But i need to know the size of the fuel pressure regulator hose which is connected to the front of the resonator. I eye balled it and it looks like its 3/16 so I will probably just use some 3/16 break line. But if any of you mechanics out there know please lemme know for sure. I know the diameter on this hose is pretty important so i dont run too lean or rich.
