My fuel tanks are vented. My fuel cans are not. Wet outside air can enter the tank when warm and drop moisture as it cools. The fuel cans not so much. They do squeeze down as it cools, and if I were to vent them on a warm, moist, day they would get water inside. I don't, so they don't.
How crazy are you about topping off your tank?

I meant the tank on the tractor. It should not be vented. Even a non-vented tank will only allow so much vacuum, though because otherwise it would implode/collapse. I don't have storage tanks. I don't use enough diesel to warrant storing more than 5 gallons.
I thought the tank on my tractor was vented? I'm not a diesel guy, but if it isn't it would be the first vehicle I ever owned that did not have a vented fuel tank.

Bob - - yes, tractor tanks are vented, often a simple vent in the cap.
Otherwise, the fuel system would draw a vacuum to the point tractor wouldn't get fuel.
Vented to let air in, not out. I didn't state myself very well. Otherwise there would be a constant smell of fuel around the tractor. I NEVER smell diesel around my tractor unless the cap is off the tank and I'm pouring more in. This is by design. Venting fuel vapors constantly is probably not the safest situation. If you look at the cap closely, you'll see what I'm talking about.
HORUSDY Gas Siphon
Do yourselves a favor and pick up an in-line gas tank siphon. You put your gas tank right on the hood of the tractor, shake the siphon a couple of times and the fuel flows directly into your tractor. Walk away and let it work! Best device I've found in a long time. Amazon and inexpensive!

Putting the tank on the hood of my BX isn't going to work, since the tank fill is centered over the right rear tire.
