fueling problem

I tried searching in here and found no threads about it, but does anyone have the same problem fueling their 67 or 60's stang? I have spent 15 minutes every time I refuel, if I pump too fast, it spits out gas or the pump doesn't allow it. Does the pop out gas cap fix this? is there anything else that I can to? I have a coupe, is there a cap relocation like the shelby's have that would help this? Anyone that can help would be appreciated.
 
There was a thread on this inside of the last three weeks, but even I searched and couldnt find it.

When I had my '65 I had to hold the vapor boot back on the nozzle and be careful not to overfill. I could tell by the sound when it got full. The biggest problem is not having a modern filler neck with the spring loaded flap that works with the auto vapor recovery nozzles.
