i was talking to someone about taking my fuel tank off the bottom of my blazer and running to full size kegs, and they told me it would just be easier to run gravity lines from them, i don't know what that is. i was just thinking about swapping my manual fuel pump to an electric fuel pump and just run seperate lines to each keg they set it up with a switch to change the tanks back and forth, for those long days in the woods or camping in the mountains. but i still dont know what a gravity line is???????????
