Here is a picture I got from SW of the Trailtech aftermarket Nytro tank. I wasn't too crazy about the white plastic that looks unfinished by the tank on both sides but I will be painting my hood and that piece black so It wont be as noticeable.
I'm looking at getting the same tank. I'm not to fussy on the unfinished portion of the plastic on either side near the gas cap. Does anyone know if that plastic piece flops around or is it fastened tight against the tank.
