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.
