Verify carburettor versus fuel injection on your specific production year

Not all P1800E models came the same way off the line. The transition between fuel systems happened across the production run, and mixing them up costs money when sourcing correct replacement parts. I've had to source obscure Zenith carburettor components that simply don't exist anymore because a previous owner made changes. Before you start ordering parts, confirm exactly what your car left the factory with and stick to that.
