Contrary to popular belief, there aren't many vehicles with "anti siphon valves", "filter screens" or "rollover valves".
However, there
are many vehicles with a long, convoluted passage between the filler neck and gas tank.
Using a thin hose and some patience usually works best.
This particular siphon uses 1/4" refrigerator icemaker water line for the section that is inserted into the tank. The tip of this line is cut at an angle, to make it less likely to snag on the inside of the filler passage as it is inserted.
Some vehicles have a spring-loaded "flapper" that closes over the filler inlet, making it more difficult to snake the siphon hose down the passage. Using an insert holds this flapper open - This one is made of a short piece of copper water line and end fitting.
On some vehicles, you can use a thicker siphon hose, which helps speed up the process considerably. So, it's helpful to have several different hose sizes on hand, using the largest one that will fit.
