The welds inside the filler neck that hold this tube together broke off and it fell inside my tank. Luckily I was able to get it out. I am using a sparco fuel cap now and I wont be using the maverick filler neck anymore. So I was wondering what this tube is for and if I need to somehow make it fit on my new filler neck that im having an exhaust shop make for me. Is it an anti syphon tube or is it a breather for the gas tank? I don't want to have fuel spilling when I'm pumping gas.
