Hi Brett,
Its a bit different layout from the GT but I believe the restrictor is to stop fuel being syphoned into the carbs. If the car was parked nose down a slope enough fuel can bypass the floats overnight to fill the cylinders.
The restrictor allows a very small amount of fuel to be pumped back to the tank, prevents the fuel line from being pressurised when the pump is not running and, as above, prevents vacuum or syphoning.

I would tend to concentrate on the ignition as Joachim suggested once the fuel pressure is sorted out.
