Vacuum Generator Replacement

Our vacuum generator started leaking air a couple days ago inside it's little black box (located on passenger side of generator enclosure). It would drain the main air tanks in about 30 minutes. I talked to Bob at Foretravel and he said parts are no longer available for this, but they have a solution. They are sending me parts for about $265.

The quick fix for the air leak was to fold the air supply line in half and tape it so it won't unfold. That is working. He said I won't need that air line because the new part is electric.

When I put my finger on the vacuum port, the pump shuts off immediately. Also, when I pinch off the vacuum tube into this can (see photo), pump shuts off, but when I pinch the tube “out”, it keeps running.

The can is needed to support the stock vacuum generator. Without the can, the generator goes belly up very quickly.

Finally got this project finished. FOT no longer has a source for the vacuum reservoir; at least not now. The factory quit making them in about 2006. A neighbor suggested filling mine with water to see where it leaked. Found the leak and he gave me a marine epoxy sealant to fix it. Now the doors in the dash HVAC work again and no air leaks!
