My apologies for plaguing the list with vacuum generator questions but
I'm trying to figure out if I can retrofit a different vacuum
generator. The original had 3 ports in addition to the threaded
supply port. The are labeled with letters "E" "V" and "s". The "V'
is the main vacuum line to the vacuum canister on the cruise control.
(I believe). The "e" is exhaust I think because this is where it was
'leaking' or exhausting. The 's' had a vacuum hose attached to it but
I don't know where it goes. Can anyone give a guess as to waht "S"
means or can you tell me where the additional vaccum line terminates?

Kerry,



I can look at mine- however, it won't be for a few more weeks.

I plan on many 'outside' projects on the bird' here in a few weeks when it
gets closer to fall- its too hot to be out working on the outside stuff this
time of year!!! I have switched all of my projects to 'indoor'.

Kerry,

I think I found it... Check this out
http://www.gtc-products.com/?id=vacuumGen

"S" - If it is a vacuum port as you say it is, could that be for a
vacuum gauge or a vacuum pressure "S"ensor as indicated in the above
link. I'd guess you do not need that second vacuum port unless there is
something more on your coach that operates using vacuum.

That's my guess.

If the vacuum generator you found is inexpensive, it can't hurt to try
one. But first I'd us a hand held (manual) vacuum tester. Hook it up to
the cruise control bellows. Pump the vacuum tester until the bellows
sucks in. Read the pressure and compare that to the vacuum generator you
found on the net.

Good luck.

Curt:
Thanks. That does look like the right kind of thing although it says
it is powered by nitrogen and not air. The one I found at Anders
was $9.95 and I'm trying to get it thru a local distributor. They
have two versions, one with more pull. I'm still working to figure
out what the additional line is. I forgot to ask Bennie when I had
him on the phone.

You might try Googling 12 Volt Vacuum Pump. There are options avalilable.

Kerry, If you find a suitable pump, I would appreciate knowing your source as I
am having a similar problem. Thanks.

I ordered both sizes of this version:
http://www.anver.com/document/vacuum%20c...ts/vacuum%
20generators/pumps-jv.h\
tm

I called Anver and they gave me the name of their local supplier who
should have them for me in a couple of weeks. I;ll let you know if
they work. For $9.95 it's worth a shot. I don't know if they shut
off once an adequate vacuum is produced. If they don't I may
install a valve in the line to turn it on and off when needed.

Hope this helps,

Jim:
Thanks, that explains it. I'm pretty sure mine had a leak in the
diaphragm. If it didn't before I disassembled it, it definitely does
now! I'm not sure the vacuum generators I have sourced have that
self-control shut off feature. Did you use the Rostra Global Cruise
as a replacement? How is the servo operated on that unit and how long
did it take to install it?

A little off topic, but. . . I just ran across this patent for a
new(?) device which claims to do precisely what you describe our
vacuum generators accomplish. Did someone fail to patent the original?
