Glad you asked that. I have the same problem with my '04 SRT-10. Does not matter where I fill up, the angle of the car relative to horizontal, the angle of the nozzle or how much fuel is in tank, can only "drizzle" the gas in without the nozzle cutting off. Been like this since day one. Any ideas?
I've never been too concerned about it because whenever I fill-up inevitably a crowd gathers, and I've got 15 questions to answer about the car which takes up all the time that it takes to fill up anyway, but some day I might be in a hurry.
