Well, Charlie -
The gravity of the situation compels me to point out that with a direct connection on a four percent ascending grade the water from the primary tender would tend to flow back into the auxiliary – or at least that forward flow from the auxiliary to the primary would require assistance – whereas even a non-lifting injector might have enough suction to draw water directly from the auxiliary tender. OTOH, perhaps the water from the auxiliary was used first, before the upgrade reached its maximum, so that water from the primary tender would be more readily available when really needed.
Just a wild guess on my part.
