i have a problem with my t maxx. i have the stock pipe on and after i run the truck there is a puddle of gas on the chassis. i know its from the pipe because theres a small gap in it. i have tried assembling the pipe back together and it looks sealed but it still leaks some gas. i know there will always be some fuel around on a nitro vehicle but this is more than usual. does ne1 know what i could do. thanks
