I am having two problems with my 03 Astro. I get a check engine light on the dash and at some gas stations I am unable to put more than a gallon of gas into the tank. The engine code tells me that there is a problem with the fuel system venting. Does anyone know what the filter is that needs to be replaced or how to determine which filter needs replacement. Thanks, Art

There is a vaccum line on the fuel tank that lets off fuel vapor so it doesnt build up in the tank, it vents off the fuel vapors so you can fill the car and so it doesnt pollute the air. From the tank it goes to the Carbon cansister via vaccum line and is resting there untill the car is started of which then it burns off the vapors. If that line is plugged up or kinked the vapors will not release.
