 The fuel pump is not an SU, but is black plastic and says "Auto Pump made in NZ"...not sure how to test the pressure, without a specific tool for the job.

The fuel is leaking out of the vent hole at 11 o'clock, if i plug that it comes out of the hole at 1 o'clock. That hole has a fitting to the vacuum lines on the outside of the carb. PO did remove the Charcoal canister.

Is there a pressure regulator I could install? Not sure if i should put in a regulator or a different pump? The fuel starts running out when the pump is on, car not running. The needle valve in the float chamber should stop the flow of fuel once full? I'm guessing the leak is either high fuel pressure or the float needle valve is stuck open? If it were high pressure wouldn't the other carb be leaking?
