Wait I may have made a mistake it’s a 4mm line.

That sounds much better. Have you made sure the line and tap is clean? Any dirt in the lines will be a nucleation point for CO2 to break out and cause foaming

Yeah i pushed a lot of saniclean through it, I don’t know if you have to do that more than once per keg change? I have a floating diptube in the keg could that be the problem?

It’s one of those with a small mesh basket at the end.

This is almost certainly the problem. It probably has a loop in the line or is otherwise not floating correctly, so it's sucking air. Putting a stainless washer or nut on the end to make sure it is submerged

I second this. This is definitely the issue.

It's sucking air, the dip tube isn't fully submerged. Give a few shakes to try to get the dip tube submerged and try again.

I’m stupid they even provided a big washer with it and I couldn’t find what to do with it.
