The bypass mod is only needed if you use the SC pump. If you use the old pump you don't need the mod. They go hand in hand. The SC pump has a smaller scavenge pump and larger pressure pump than the old pump. If you don't do the mod and use the SC pump the crankcase may not scavenge properly and you could have the tank go dry.
