1/4 inch line is not going to cut it.
Your pressure drop on that is insane.
I would be considering a repipe.
Here’s one basic pipe sizing chart
And then all devices and fittings and bends will add to your overall piping length this is usually called the “equivalent pipe length”
Which is the kind of length these charts are talking about not just your linear footage.
For example the refrigerated air dryer might have a equivalent length of 30 ft of pipe.
And I’m not sure the inside or outside diameter that 1/4 flexible airline but usually tubing ends up being a smaller inside diameter then piping.
An example of this is half inch PEX versus half inch copper or half inch black Iron.
Another huge restriction is having fittings that fit on the inside diameter of the pipe instead of the outside diameter the pipe like sweat on fittings for copper or thread on fittings for black Iron are on the outside.
Where something like a barbed fitting or PEX fitting will fit on the inside and have a higher loss.
