First, a plumbing problem would NOT necessarily indicate an oil leak, as the plumbing may be blocked and not ruptured. As could the gauge. Again, I'm no expert on your car/engine. I hope you have a workshop manual of some kind to assist you along this path. The last thing you want to do is pull the pan to get to the oil pump, and this is what I am trying to point out. If, in the end, it points to a defective pump, then you can decide how to proceed. Of great value would be to have a schematic diagram of the engine's lubricating system and a complete understanding of the pressure relief circuit.
I've just looked up your pump on the Autohaus AZ webpage and it apears the pump has a tang/dog which is driven by a slot on the end of the distributor (my guess), and not a chain or gear. You would need to confirm this by removing the distributor, expose the distributor driver slot and see if the tang is not broken on the pump. If you opt to pull the distributor, remember to rotate the engine to TDC on number one cylinder. This is important! Place a witness mark were the distributor rotor points to the distributor body. This will allow you to replace the distributor in the correct position during reassembly.
Please post your findings and keep us apprised.
