i dont know about that one man...gas is a tricky thing to work around...you decide to weld..like he said...the welding could ignite the gas on the tube...if you were going to do that safely and smartly..i would suggest replacing the WHOLE tube right from the tank so that its once piece...and also make sure get the gas level pretty damn low so that you dont have as much a risk when performing the mod on a full tank of gas, personally i wouldnt do it..cuz not only do you run the risk of igniting gas and or screwing up the tube...but you also run the risk of making the tail light like..well..shitty, if you mess up the taillight placement everyones going to be able to tell that it comes off..it might even look like it was in an accident and its loose or broken
