I may be floating a bit off-topic here, but someone raised "long term" storage. For long term storage I would be more inclined to drain the tank. Run the tank down to less than 1/4 full, then park it. Remove the fitting at the carburetor, attach a length of 1/4" tubing, then open the tank valve and drain the tank into a gas can set between the front bumper brackets.

It's common practice to drain fluids when storing a vehicle for long term. Also to jack up and support under the frame so the tires don't take the weight.

But a lot depends on just what "long term" is. Over the winter I'd drain gasoline and (if you live in an area prone to freezing) water. For a few months oil is fine. Longer, I'd go the full route.

Also take the battery out and store it where it won't freeze.

Fortunately, where I live in NorCal we can drive 12 months, and don't have hard freezes where I'm concerned about water cracking a block/head.

Oh yeah, I second (third? fourth?) the recommendation - don't put water into your tank.
