I made a fuel pump gasket for a Kawasaki Vulcan about three years ago and that bike is still on the road and leak free, so there’s an endorsement for you.
Yes, TPU is impervious to gasoline. It’s not impervious to heat, though, so it’s no good for valve cover gaskets, head side intake gaskets, or various other engine-adjacent applications.
