Fuel Hoses Lines/piping And Fittings problems of the 2001 Jeep Wrangler

Hi my complaint is that when my vehicle is started there is a strong scent of fuel. This smell continues until the vehicle warms up then it ceases. I also get approximately 80 miles less to the tank on gas mileage. I have talked to numerous persons of whom own Jeeps, 2000 or newer and they had the same problem. Most of these were noticed while still under factory warranty, so the problems were simply fixed. Essentially they were given a new gas tank and fuel lines to fix the problem. I would just like to put out there that there is a strong smell of fuel which could lead to a very serious problem. Please let me know if anyone else has complained of this or had any problems of this kind. Have a wonderful weekend. Kevin champaigne.
