But the thing is, it's liquid and the valve prevents the fluid from going anywhere so in the hose, pressure will be higher...
The pressure of the fluid will be the same in the cylinder and the hose, the area of the hose is smaller therfore has lower "area" load(for lack of a better word).

This is why smaller diameter tubing can handle higher pressures at the same wall thickness.

No. Your understanding isn't quite right.

P=pressure
A= area of the piston
F=force

P x A = F

Now solve the equation for P

F/A = P

The greater the area....the less pressure with a given force applied.

If you apply 1000 pounds of force trying to compress your toplink, and your piston area is 10sq in....you have 100psi.

Same 1000 pounds but your piston only has 1 sq in, you have 1000psi

What part of that do you don't understand so maybe I can better help

Ok I get it. Having more surface area reduces the pressure of the fluid internally. Using my example, it would mean the piston would 'try to displace' less fluid with its higher surface. A smaller surface having the same force applied to it you 'try to displace more fluid', creating more pressure in the fluid.
