Fuel rail port?

Just cracked fuel rail port. The piece that the Schrader valve goes in, while removing gauge. Any ideas on size? I saw this online, just not sure

In just bought a 4an. Guess it will be returned if that's the case. Guess I'll try npt . I knew this piece was going to be a nightmare

Re: Fuel rail port?

It's not, it's small and uses a o-ring for a gasket iirc. A hydraulic shop may have something close or get one from a parts car. Think V6 may use the same thing along with other GM vehicles of the day.
