Well then he is golden there to since a BG400 uses a pump bypass as well.
In the context it is being referred to hear they are talking about return style system after the regulated fuel to the carbs, not at the pump or unregulated fuel. My comments are toward the system being discussed. Don't believe in return systems from the carbs back, bypass at the pump yes.
The direct pump bypass systems are on lots of fast cars but so are deadhead systems but my experience with the Aeromotive hot rod pump when bypassed was no volume left to feed my motor. You could hear the motor struggling to make power on the second half of the track even though the company said it was fine but it wasn't and the Magnafuel 300 system totally rocks and drives fine for long trips on the street.
