I was looking for more information before purchasing this product, but never found the description I needed. In case someone else wants it, the tubing is 6 feet long which seems to be enough for what I will want. It also says it can be attached to a garden hose with a 1/2" adapter. The tubing has an inside diameter of about 1/2", and the packaging claims it will siphon up to 3 1/2 gallons a minute. It says it can siphon gas, diesel and kerosene as well as water or oil and should be cleaned thoroughly before storage. Even after cleaning, I would get separate siphons before using the same one for different uses.
