Bit of a pain every time I fill up in NJ where it is illegal do do it yourself but really the only way some gas ends up in the tank and not down the back of the car and on the ground! I just have to use the Gas stations that 'allow' me to fill up myself. Do i need a licence to pump gas or what?
Seriously, the aero filler I have and large pipe still makes no difference, I suspect a large vent somewhere would help through.
