    LOL

    you've hooked up a EFI fuel pump to a carby engine, carby fuel systems are only designed to run at a few PSI, while an EFI pump operates at around 50 psi or so.

    so yes, you're pumping shit loads of fuel into the float bowls and its over flowing into the engine more then likely.

    dont people research before carrying out mods these days?

    Im suprised that the fuel lines are talking the efi fuel pressure, they will proably break soon and it would become dangerous, I would suggest not driving the car.

    Would a fuel pressure regulator help matters?
    Just a thought, not sure if it would work though.
