I've been reading the messages about the DG-400 oxygen system with some
interest.

In the DG-1000 that I often fly, we have a US oxygen bottle, the AL-647
listed on the Mountain High site:

The DG-1000 has a factory made oxygen cut out that can accept a bottle
up to 5.5 inches in diameter and 29 or 30 inches long. The AL-647 is
the only bottle that fits but is only 19" long. There appear to be no
other [longer] bottles with a similar diameter that we can get.

The problem is that even with a decent fill and the EDS system, two
pilots flying at high altitudes (16,000 feet or so) will run out in
about 6-7 hours with that tank.

That seems a bit quick for an EDS system. It would be worth checking the
output pressure of your regulator, which should be 15 psi. If it's
higher than that, your consumption will be correspondingly higher.
