Hi folks, I'd like to be able to siphon gas from the tank of my Explorer periodically for my gasoline powered toys. When I stick tubing through the filler hole, I reach resistance at about 3 ft I can not get past. Is there something preventing me from reaching the gas? Any idea how to easily access the gas in my tank? Thanks, -J.R. P.S. I don't plan to suck on the tube to get the gas - The tubing I got (at Walmart) has a hand squeeze bulb that will prime the siphon.
