FX Crown Continuum Fill port extender

Hello! I recently purchased a crown continuum on the forum here for my dad and I’m about to go deliver it to him but realized my compressor won’t connect to the fill port. It looks like it should connect, but I can’t get it to make the connection. I know FX have recessed fill ports, so what exactly do I need to make it work?

I found on Amazon a “8mm Quick Disconnect Adapter” that claims suitable for FX Airguns which can be delivered in a few days.. is that what I need? Sorry for the newb question. Thanks!

If I can’t get what I need in the next few days, no big deal. Was just hoping to go shooting with him. Guess I shouldn’t have waited to charge it the day before heading over 🤷‍♂️
 
You need an extended female foster. I'll post a pic in a minute. You can find em cheaper if you look around. Some FX guns have deep set fill fittings that can make it difficult to connect. Make sure the male foster is centered in its hole in the stock too.
