this might contribute to my bad MPG, the grommet is bad i think, b/c everytime i had alot of gas in the car, like when i just fill it up. If i turn left, gas spills out the side of the car. not out the filler hole. under the quaterpanel. I think where the neck meets the tank, there is a grommet there isnt there, How hard would it be to replace???, could i just pull the filler neck out and put a new one in, or would i have to pull the gas tank??
