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

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.
