The AN 4022-1 is the final fitting that goes into the cylinder head that injects primer fuel into the intake port on a typical opposed carbureated aircraft engine. This fitting is fully machined with a precision fuel atomizer inserted into the machined body which explains the price difference between this item and a typical fitting.

The (AN780-2 brass primer fitting)is not a primer fitting. AN780-2 is a 1/8 pipe thread to 1/8 cone fitting. Most commonly used in a primer system. This is a bad nomenclature description. AN4022-1 is a primer discharge nozzle or fitting.

Took me a while to find these actually existed. Should have called sooner. Thanks
