I had problems filling my tank took forever cause the nozzle kept shutting off no mater how I held the pump handle I could put gas in one squirt at a time I experienced this at 2 gas stations. The gas stations I normally use near my house are okay except I need to lift the handle up otherwise I can pump at full speed. So for me its a pump dependent issue to me the tub from the gas cap to the tank seems awfully narrow about 1", must be part of the issue.
