You should be able to safely drill out the centre of the buffer tanks valve to 3/8 dia....... thus improving the flow GREATLY.

Edit ......Mario mentioned your valve...I have just realised that the fitting between the buffer and the manifold could well be another restriction... Maximise both the buffer and fittings thru holes.

What are you using as an exhaust on the ram........a small bleed hole ?

Have you added a cranked dip tube to your main supply tank?
