True, as long as you did not let the pressure increase. But it will take the volume of the line for every 14.7 psi to bring it up to that pressure in the line. Then if you open the line you will lose that pressure and have to replace it. So for 50psi line pressure you will need aprox. 4.5 times the line volume of gas to get that pressure.
So for the example: 1/4" ID 100' hose: it would be about 265 cubic inches of gas. Or just over .15 cubic feet, not counting hose expansion due to pressure.
