1.5" pipe has an area of 1.8 in2. So if your surge box is 12" tall thats 21 cubic inches( or 0.1 gallons) of water holding the flapper closed. So that is almost a full pound of weight.

It should be dependent on the size of the flapper though not the size of the pipe as it enters the tank. I see what your saying though about total force maybe the fishing line needs to be shorter as well to reduce head pressure? Although Ive read other suggestions to increase the head pressure so that the flapper stays closed longer allowing it to "pop" when it finally releases. The flapper is lifting its just not lifting with enough force to fully pop up. At no point does the water reach the overflow pipe. Hopefully another float will solve my issue
