Does a 12" x 1.5"D tube filled with 10psi have more force on an piston than a 6" x 1.5"D tube filled with 10psi?

Or is 10psi the same on an object no matter what size the tank...

What is the area this pressure is acting on? Is it the same or different between the two cases?
 
The area of the piston would be the same.
 
Lets say you have a conventional bicycle tyre pump (eg piston in a tube). The force you need to apply to the pump handle depends on the pressure in the tyre and area of the piston and NOT the volume of the tyre.
