Got my GT in Sept. 05. I have been experiencing this problem from day 1. Finally got fed up with it and took it to the dealer last Monday. They ordered a new tank right away. No hassle. Tank came in yesterday, hope to have the car back tomorrow afternoon. They gave me a brand new Ford Focus to drive all week while they had my car. Man does this thing run. I went from 0-50 in 18 seconds. I get all kinds of looks from women as I pass by them. Mostly looks of disgust and pity. Please give me back my mustang.
