No revenuers on this trip! I know what you mean about the vacuum tank. For years I have carried a small gas can with me in case I needed to refill the vacuum tank. I have rarely needed it. But it is nice to have, just in case, like a spare tire. Once time a while back the vacuum tank failed on me and I had to refill the vacuum tank several times to make it home. The center wire managed to cut through the upper cork, which caused the tank to fail. The fuel can pictured is really an old kerosene can. Since it has a small spout, it works great for filling the vacuum tank.
