Where is the overflow vapor senar located


If this is related to the fuel filling, evaporative canister issue, maybe the following will help. Most of the components for the fuel tank are located near the tank itself, with some near the front of the tank and the evaporative canister components behind the driver side rear wheel inside a splash cover.

The biggest problem people complain about is not being able to fill the tank without the pump stopping if the tank is filled at a higher rate than a trickle. This issue is caused by trying to overfill the tank after the fill nozzle has clicked off causing fuel to damage the evaporative charcoal canister clogging it and causing the blow back to the filler neck and fill nozzle, simulating a full tank shut-off of the filling process. This is not exclusive of Hyundai, and gas pumps usually warn of overfilling the fuel tank because of this known result. This evap containment mechanism was developed for the cars to replace the vapor collecting mechanism that gas stations used to use partly for the fill nozzle and collection dangers, now all that vapor is collected and safely burned when the engine is running. The evap canister can be expensive to replace, in the neighborhood of $150 from the dealer, and it's not recommended to try and bypass the system or you can create more issues than you solve.

If this isn't related to your issue, sorry, maybe you can post more info on what the issue is and how you need help.

2000 CHEVY S-10 FULL TANK OF GAS ENGINE LIGHT COMES ON AT HALF TANK LIGHT GOES OUT WHY?


You may be overfilling the tank. The fuel tank is connected to a vapor recovery system. If you over fill it it will be drawn into the recovery system and kick the engine light on. By the time you have run a half a tank of fuel thru it, it has cleared. Try stopping the fuel fill when the nozzle kicks off and not trying to get that extra 2 dollars worth in it and see if the helps.

Where is the fuel filter on a 2004 dodge stratus, my engine light came on after filling with gas, then went off, today it is on again after I gave it gas to take off and the car choked, so I gave it gas...


did you stop fueling as soon as gas pump clicked off or did you keep trying to add extra fuel . some vehicles if gas tank overfills fuel fills into evaporative system and causes check engine light to come on.

Engine light after i overfill gaz tank 2004 4runner


The light didnt come one because you filled it =while it was running, its on because you overfilled it. You pushed gasoline passed the rollover valve, into the charcoal canister which is probably now saturated. It may push raw fuel into the intake, which will make the engine run rough. Chances are, you need a new charcoal canister, ORVR, corrugated hose, and Purge valve

Why do they tell you not to overfill gas tank


The actual reason is maximize your fuel mileage.
The engineering is as follows:
There are times when the fuel injectors shut off when you are driving, like going down a long hill. There is no need for the injectors to "work", as you are coasting without giving it any gas. But, the engine will stall out with no injector action. So, how does Toyota keep the engine running? From the gasoline FUMES in the fuel tank. There is a tube on top of the fuel tank whch siphons the fuel vapours...The vapours then are stored in something called a charcaol canister, in which the "charcoal" absorbs the fumes from the tank, and, when coasting, the injectors stop injecting, and the stored fumes are admitted into the intake manifold thru a valve controlled by the Electronic Control Unit, or ECU. The fumes are used by the engine, thusly maximizing your mileage, other than losing them by letting them escape out from under the fuel cap. Now, to answer your question: If the vehicle is "overfilled", there is no place for the fumes, other than in the top of the filler neck. And the siphon tube is on top of the tank. The ECU sees the overfill condition as a "blockage" in the fuel fume vent line (only fumes should be in this tube), and said "blockage" will transmit this to the ECU, thru a sensor, & turn on your check engine light. The overfill actually "lies" to the ECU, even though there is nothing wrong. Best thing to do: When filling the tank, stop after the handle clicks off.
I hope that I have explained this to your liking.
