Is anyone using the Hi-Flo Fuel connectors, I am looking into this upgrade, any input would be appreciated. Mileage drop? Hp gain? Driveability issues? Anything. Is the dual feed line worth the money? They say its worth 30-40 HP on a stock CP-3? I've heard of some leaking and never being able to stop it from leaking. Does it hurt to bypass your relief valve? I know the CR uses a return thu the injectors as well the relief valve, but how critical is that valve?
