Cars and anti-siphoning devices

Like many people, I thought I would be able to tap into the fuel in my Honda cars last year. Aparently there are anti-siphoning devices installed in the Hondas (I don’t know about other brands) that prevent a hose from getting to the gas in the tank. There may be a way to do this, but I have not found it. The anti-siphoning devices are actually safety devices that prevent large amounts of fuel spillage in rollover accidents, they are not just fuel theft prevention devices.
