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.

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

This item has fine brass threads.(NPT) It is designed to be threaded into the intake manifold of my Continental engine. The threads needed cleaned before I could get it started. Not a big issue for me but someone may try to use a wrench and cross thread it. Suggest contacting the manufacture about this. This fitting is the fuel prime nozzle.

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.
