Your profile says you're running twin 40's. I've got twin Dellorto 40's on mine with electric fuel pump, regulator, and pressure guage, and I have my pressure right around 3 psi, slightly under. Hopefully you have a fuel pressure guage, it is crucial running this setup! Weber/Dellorto's aren't recommended to go any higher than 4 psi, with 5 psi as the max. Make sure you have excellent electrical connections (sanded off ground and power connections) and are using thick power wires. Also, make sure the fuel pump is as low as possible, preferably below the tank. If it isn't mounted low, the fuel will not gravity feed to the pump, making it almost impossible to prime the pump and get it pushing fuel. Try priming the pump by sucking on the fuel line, but watch out for fuel when it does come out!!! I have my electric fuel pump located just under where the stock fuel filter mounts on the right side of the car in the engine bay with no problems. Mine fired right up and ran great, even better with more tuning of the fuel pressure. Good luck!

I am puting on a weber 32/36 (holley 180) carb soon and I have the existing fuel pump (mechanical) - can I get away with this setup or if I do need a elec fuel pump what are the brands/models to get?
Cheers

Keep the fuel pump as low and as close to the tank as possible, if you are running a carb you won't need any more than 8 PSI pressure.

Depending on what carb you have will dictate what fuel presure you need. If you have a hitachi, watch the float bowl window, and see if it is staying full. Hold it at say 4000 rpms and check to see if its still keeping fuel up to it. If the presure is too high it will flood your engine. I had mine so high once that at idle it was running rich, and when I opened the throttle it stalled . Then when I tried to restart it , the motor hydraulic locked!
