This was the guy that held a small can to catch the overflow of gas that spilled into a special tube when the gas man filled the gas tank on a race car. In 2011, Nascar no longer required the use of the catch can man. They now use self-venting gas cans.
Try this site, (it's not an official gas can):http://www.amazon.com/Wedco-NASCAR-Racing-Style-Gas/dp/B0002CX9D6http://www.pitstopusa.com sells Richardson fuel cans, which are NASCAR-sanctioned.
Actually, the gas can itself can only hold 11 gallons of gas, that's why you always see the gas man putting in two cans worth of gas during a regular pit stop. Yes, 11 gallons is what the can is suppose to (and designed to) hold, however, there are some very clever people in Nascar who got as much as "11.7 gallons" from a can, neck, an vent included. That coupled with oversized gas lines, vent tubes, etc., consider stronger tube material with thinner wall thickness. every aspect of race(car/truck/etc.) is scrutinized for what ever edge they can get. Mileage is very important in winning, gastanks, cans, lines, are well thought out. Though at some tracks, NASCAR mandates a smaller fuel cell to spread out the field (like Daytona and Talladega)

Because they gave NASCAR more money.
Normally cans(soup cans, soda cans, etc.) are made of aluminum.
No there is no maximum in NASCAR.
When rhubarb reacts with steel cans, the gas formed is hydrogen gas. This reaction occurs due to the acidic nature of rhubarb, which can corrode the steel cans and release hydrogen gas as a byproduct.

Gas cans are used to transport gasoline in a small container to fill motorized equipment such as lawn mowers and snow blowers. These gas cans are also used when a motorist runs out of gasoline.
Gas cans are available in an assortment of sizes.
NASCAR was started by Bill France Sr in 1948.
