Not all long range airplanes have dump systems. The 767 and 757 are long range and yet most do not have dump capability. Only 767-300 models and then not all 300's. All aircraft must demonstrate a landing with a max fuel load anyway (even when they have a dump system) to be certified. If an overweight landing is made a maintenance inspection must be done. The FAR's describe when dump systems are required and I believe Boeing obtained a waiver to certify the 757 and 767 without such systems.
