Nissan 2004 sentra fuel filler neck

nissan 2004 sentra fuel filler neck, fuel will not flow in freely, constant pump shut down and spill back occurs. venting issue???- help!!!

There is a simple trick here if the fuel neck is not damaged in some way. Just pull back 3-4 inches on the nozzle and tilt the handle down. That allows the fuel neck to vent and take gas easier. Some vehicle fuel necks are so small you can only use the low to medium fill volume setting. The high setting will spill back on most compact cars anyway.
