Air drain port valve leaking on 2000 Windsor

[Ali-026]

Hello Everyone

I've recently replaced the front HCV and used the drain port valve to empty the tanks. After this work, I've noticed a slight leak from the core of the drain port valve. Please note it's the center rotating part that is leaking, not the valve itself.

Does anyone know the port size (1/4 NPT ?) for air drain and any possible replacement valve suggestions?

Thank you

Ali
