Air leak

[Chuck Wheeler]

Sounds like you found the Vacuum generator! If working properly it will
shut off when the vacuum reaches a "set point". If you have a vacuum leak
in the cruse control it will continue to vent air to make up the lost
vacuum. I replaced my cruse control with a Rostra Global Cruise when my
generator quit as they are not available any more. It worked with the
existing stalk control and speed sensor.

Subject: [WanderlodgeForum] Air leak



I have an air leak in the front of my 78FC33. Lying on the ground
and reaching up in the left front there is what looks like a
distribution valve. It has at least two thin black hoses attached
with screw on caps. When I shut off the coach it leaks for a few
minutes then stops. The brake tanks keep about 75 lbs of preasure,
but the step stops working.

There is a tube that is designed to have a rubber hose sliped over
it on one side of the valve, I can't see it, but that is where the
air is leaking from, It seemed odd that there would be a slip on
connection when all the others are the standard black tube with a
screw on connector.

Does anyone have any idea what this valve may be for? I had read
that the cruise control used air passing over a venturi to generate
vacuume, could this be it?

Thanks
Gardner
