CIS Question

I've got my newly purchased fuel pressure gauge from JC Whitney, and I'm ready to test my system and control pressures over temperature. To insert the fuel pressure gauge into the circuit, I disconnect the connection between the fuel distributor and the warm up regulator. When I'm done, the Bosch book says to replace the O-rings in the connection at the fuel distributor. Are these O-rings available at regular auto parts stores, or do I need to order them or get them from a Porsche dealer? Sorry about the trivial question, but I've never tinkered with the fuel injection system before.

I bought several from the Porsche shop where I get service done so I would have extras. I also bought several of the copper crush gaskets for the fuel banjo fittings as I have had to replace one or two over the years.
