Thankyou to all that responded to the hydrovac emails. I do indeed have a
hydrovac on my 46 2-ton. It is the later '46 model that Bob Adler refers to
with the air can (Bendix Aviation Corp), near the battery tray. I have
decided to stick with the original stock setup since it seems to have worked
fine. I am rebuilding the whole truck anyhow so the system will be in effect
"new" when I am through and should last a long time with proper maintenance
as Bob recommended. Thanks to all for your help.
