Why does it take forever to fill has tank?
The past few months when I attempt to pump gas in my car it keeps shutting off like the
tank is full. It wasn't full. In the tank it sounds like it's full of gas but I had just started
pumping. I tried several different pumps and the same thing happens. It only works when
I barely have the pump running
You gas tank vent is plugged up. You May be able to replace the rubber hose that runs from the filer
There is a auxiliary vent solenoid that blocks up causing this hard to fill condition. Its under the rear of vehicle behind the gas tank on the lh side. It's simple to replace but is expensive. I believe it is under $200.00
