Modern cars have thing called evap canister. It is carbon filter installed on fuel tank vent. Problem is thank many people top of tanks to above it limits and gasoline instead fumes reach that filter when tank is overfilled. Once gasoline enters filter it became solid and prevents fumes from escaping tank via filter.

The vent solenoid "closes" the fuel system while driving to allow fuel vapors to be burned in the engine. If your vent solenoid is not operating, this is a condition you will have. Get the vent solenoid tested.

Can only pump fuel very slowly into my 2003 2.7 litre Kia optima. Why, and how to fix?

Check that the flap/valve that moves aside when you insert the fuel nozzle is moving fully. Also check the rubber tube on inside of the fuel filler cap to the tank is ok .. and often, there may be a thinner tube that acts as a vent... check the vent tube (if fitted).

When you fill your car with fuel the back pressure from the vehicle fuel tank causes the fuel nozzle to cut out and stop delivering. This is just a safety feature. Every fuel nozzle in the world is the same..

You don't have a big problem. Next time you refill with fuel try delivering in short 'spurts' .. pull the trigger for a few seconds and then release .. pull again ... Let the pressure in the tank drop between spurts. Don't shove the nozzle into the fuel filler and try and blast gallon after gallon into the tank.

I'm in the UK. I have a 1998 Jeep. Every time I fill it with gas it takes a while and my wife phones the police to report me missing from home... You don't have a problem. Fill it with spurts..

2003 kia Sorento gas keeps spitting back out when I try to fuel up

There's usually a flap on the fill tube below the gas cap. Try to put the pump handle past the flap, and slowly pull the pump handle to fill the tank.

Gas gauge goes to empty after fueling my 2003 kia sorento

Hi. could be a number of things but a likely guess is the float on the in tank sender has sunk as it happened when you filled up. I don't know the sorento personally but often under the back seat there is a black plastic access panel to the fuel pump and sender assembly. under that will be the pump assembly with a 4 pin plug. 2 thick wires to the pump and two thin wires to the sender, If that's the case link out the two thin wires and the fuel gauge should go to the top with the ignition on. That will prove if its the fuel gauge sender. Jon

Why is gas spitting out the filler when attempting to fuel my 2003 kia sorento

Unfortunately it's a manufacturing or maybe design fault. They all do that. It's the way the filler pipe and it's breather pipe are shaped. After the tank gets to about 9 liters before being full, the fuel covers up the breather pipe, so the air pressure builds up in the tank, compressing the air, and blowing the fuel back out the filler. It used to take about 5 minutes to fill the last 9 or 10 liters. If you do it slowly, which is difficult due to the auto switch off of the bowsers, it can be done without getting fuel all over your feet. It's a small price to pay for an otherwise great car!

As im fueling up gas comes out fueling tube have to fuel up slow on my 2004 kia sodona

take a wire coathanger and make a small hook out of it with a pair of pliers..make the hook small enough to go in past the nozzle door in the fill pipe..using the entire length of the wire run it in and out of the filler and look for any obstructions inside(like a wadded up plastic bag or similar item) this is a prank thing with kids..if it a salvage yard about another may have a collapsed hose under the can also blow air into the tank and see if the vent hose is plugged up..

Why is it difficult to put fuel in? Its very slow and if go to fast, belches it back out.

The fuel tank filler neck has a vent tube running along it that lets air escape as you fill the tank with gas, this tube is more than likely kinked, this causes it to be slow filling and belch back at you when trying to fill the tank. In order to correct this permanently you need to replace the filler neck of the gas tank. This is a common problem on this make of car and its sister car Hyundai both are made by the same Korean car company.

The vent tube on the filler neck is probably clogged or pinched somewhere. If you get under the car and look at the filler neck you should see another tube coming from it... that's the vent tube. Either try getting a piece of wire through it or you might be able to blow compressed air into the tank. One of those methods should clear the blockage.

2003 KIA Sarento - trying to pure gas in filler tubr to gas tank

i used to have the same problem with one of my older ford trucks. what happens is because the gas is filling up the tube so quick, it forms a reverse vacume and causes all the gas to come back at you. all i used to do is when i went to get gas i would have to not pull the lever on the gas pump as hard (bout half way) and it would take the gas very nicely.
