Those pumps were also used on the Montana van so I assume they are still
available from GM. I think the Thomas pump(s) would be cheaper and would
certainly raise the coach a bunch faster.
You can get away with using a single pump for the ELII but if you do you can
only do one thing at a time (lower 1 or both side, or raise 1 or both sides,
but you cannot lower one side while raising the other). I have a schematic
for this if you want it. It required a total of 6 relays (2 extra) and one
extra solenoid valve. The relays are all the $4.00 auxiliary lamp relays,
the new valve would be similar to the existing hold valves.
I don't know if the compartment is long enough to hold two 317 pumps on the
floor so you may have to mount one on the floor and the other above it on
the wall. There are some drawings at http://www.mumert.com/ELevel2.htm for
upgrades to the ELII to connect the hold valve so it is only active while
the system is raising or lowering.
The GM pump has a solenoid valve inside the pump to release air for
lowering. If you used the Thomas pump you would need to Tee in lowering
valves between the pump and the hold valve.
The local auto recylers sell those pumps for $9.00 Canadian with a 90 day
gaurantee. If you want some tips on how to find good ones just let me know.

. Are you an electrical engineer?
