yes true. what i heard, for DNA, GPR is the only one streetlegal. not sure why LV isn't. or perhaps LV can't fit DNA? haha. for the spilling of petrol, somehow, at the opening of the tank there's a small hole to prevent overflowing. so when u pump fast enough, the petrol rises, hit that hole, and thats when all the excess petrol gets siphoned out. my 2 cents.
