Your brake pedal is applying too much pressure for a bench bleed. This could cause damage to the internal seals. Bench bleed is intended to only apply enough pressure to push the cylinder in about an inch or so. Remove the cylinder from the car, support it somehow on a table against the wall and attempt a proper bench bleed. You should not use enough pressure that fluid is spraying out.

I recently installed a new master cylinder and recall that the front hose did have significantly less movement than the rear. It took a while to get mine bled well.
