Mate if you are just running a NA setup with say a single carb, any EFI fuel pump will have too much pressure. I have this problem in my Ford ute. It runs an EFI fuel pump to a single Weber (42ml or something, downdraft). The fuel pump has so much pressure that it pushes fuel past the needle and seat and floods the car on start up, you can actually see fuel pouring down the carb when the fuel pump is on but the car is not running!

What you will need (same as me) is either a fuel pressure regulator which I think someone might have mentioned. This will bring the pressure down to something that wont push fuel into the carb.

The other option is a special Electronic Fuel Pump for a Carby car. They are avaliable at Repco or Burson's or similar places. All you have to do is connect the pipes.

I had a mate on another forum check out some info for me on Ford Fuel pumps:

Ford XF Falcon EFI Fuel Pump - 250kPa = 36Psi(?)
Ford XF Falcon Carb Pump - 48-56kPa = 7-8Psi

The carby pump was run off the engine like a 1200 one but it gives you an idea of the difference in pressures.

I might check out some prices for the electronic fuel pumps for carby cars (low pressure ones) and get one. I assume it would be cheaper for one of these than a pressure regulator and less stuffing about.

Cheers,
