Stewart Vacuum Fuel "System"
With due apologies to Pete, I have now determined that the vacuum
tank on my '28 neither pumps, sucks, draws, lifts nor pulls fuel from
my gas tank, subsequently delivering it to the carburetor. I read
"somewhere" about "someone" who rebuilds these marvels of 20th
Century technology. Can or will someone please let me know who this
was/is ? Mine is a Stewart Model M-110 as I remember.
To try to anticipate questions about vacuum tightness: I think that
it is relatively leak-free. The problem "seems" to be that the fuel
is just not released from the second chamber to the carburetor when
the engine is running.
If I break the vacuum to the tank, the engine will run until the tank
is completely dry. With vacuum, the engine dies after the bowlful in
the carburetor is gone. What I originally thought was a carburetor
problem seems to be in the vacuum tank. I do not have any
information about the innards of the tank but I think I kind of
understand in general how it works. If anyone has technical info, I
would appreciate it muchly.
I bet this info is in the '28 Shop Manual cunningly hidden somewhere
in the Bermuda Triangle, huh?
