On my BDR the vent line pick-off is approx 4" down the filler neck on the onboard side. Standing to the side of the car and relaxing the nozzle against the fill hole points the fuel right at the vent line. What works for me is placing the gas handle aft so the fuel shoots the the fwd side of the filler neck pipe or ensure the nozzle is aimed straight down the filler neck while filling if you have to stand to the side.
