Anyone have the thread size where the schrader valve goes into the fuel rail on a 85 305 TPI.
thanks

Unscrew it and have a look. It may be the same as the side that sticks out. In which case it would be -4AN.

That is what I will end up doing. I am putting a pressure gauge outlet in and want to keep the schrader valve in the system. I live on a small island and it is a long trip to town for parts so hoped to be able to get parts before I took it apart.
thanks

If it's of any help, you can decore the schrader valve!
