Hi Jennifer-
I believe I may be able to help you with the gas spillage you are having when filling the tank. This happened on my 1998 Toyota Camry.
One day, even though I was low on fuel, the attendant had trouble adding gas to my tank. Gas would spill during filling or the nozzle would click off (as though it was full) even though it was not. I had to stand there myself and slowly add gas until the tank was full.
I learned that my car had a thin vent tube that would run from the gas tank to the gas tank opening. As gas is rushing into the tank during filling, the air that is being displaced from the gas tank escapes through this tube. This tube had rusted closed a bit and was restricting the air flow escaping from the tank during pumping causing the problems I described. Once this tube was replaced, my problem was solved!
Hope this helps!

Check for black smoke out of the tail-pipe when the engine is revved. Black smoke means unburned fuel. The most likely culprit is a plugged air filter/air intake. A plugged exhaust, especially the catalytic convertor will kill your fuel economy and power. It may also be in need of a good tune-up (spark plugs, filters, ignition wires, distributor cap/rotor). Also check tire pressures and make sure that you don't have any seized brakes.

Every time you try to pump gas, the gas pump shuts off every 5 seconds. Doesn't matter how slow or fast you allow gas to come out. Doesn't matter what gas station. You never know when it is filled. Gas...


try disconnecting the fuel line leading into the fuel pump, let out a little fuel, then reconnect it. then disconnect the fuel line leading out of the fuel pump, letting out a little fuel.
if that doesnt work, run the car completely out of gas once. turn the engine over a few times while empty.
have you tried pumping gas with the enigine running? see if that helps. if this does help, it is probably the vacuum someplace, near the fuel injectors?

Dodge dakota 2005 -check engine light(gas cap)gas cap was replaced.Fuel spills out when filling tank.Fuel lines were smoked and no clog was found.


There is a check valve in the filler hose to stop fuel from coming out seems yours might be stuck , run a metal coat hangers inside the filler neck while prying open the little fill flap. see if that helps OR you are not or have no VENT to AIR in your evap system causing excessive tank pressure.

Turn the handle 1 way or the other to follow the path of the fill spout as it is at an extreme angle beyond the filler nozzle portion.
