Question about 2003 Kia Sorento

1 Answer

I own a 2003 Kia Sorento. When I add fuel to the truck the pressurized fuel system causes the fuel to splash back out of the fuel tank as though it is full and it is not. I have had my fuel pump replaced, the canister close valve and filter. The only remedy I have is to add the fuel slowly. However I am concerned that something is malfunction and that this ongoing issue could be a safety issue for me and may family. In addition the truck now hesitates to turn over when I start it. It is not the hesitation that is related to the starter I almost feel like its the fuel not getting to the engine to allow it to start. If I turn the key back twice then the engine fires right up. PLEASE HELP I have ony had the care 30 days and would like to keep it if the issue can be resolved. If not I am prepared to give it back to the dealership to select another vehicle.

2011 KIA Sorrento 2.4 were is the fuel pressure regulator located. put on adjustable fuel reg .need to disconnect stock one


fuel pressure regulators are normally located in the fuel manifold. They are either vacuum controlled or electronic controlled to maintain the right fuel pressure for engine requirements and to shut off the fuel pump when the ignition is turned off
If your manually adjusted unit will not do all that then you are asking for fault codes to appear and all sorts of problems to occur

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.

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!

On a 05 kia sorento water in gas tank removed it and fuel pump got all water out poured 1and a half gallon of gas back in tank and the kia sorento still want crank what do i do next


when you say crank do you mean the starter won't turn the engine over-can you hear the fuel pump run when you turn the key on-you might want to dump a bottle of heat gas line antifreeze in to absorb any water left in fuel system-cheers Denny

While putting gas into my 2003 sorento, the gas will come back up and out of vehicle.


Normally this shouldn't happen unless you are over filling it. If this is happening then its possible something is blocking the flow of fuel in the fuel filler hose. Air can also be a factor but I just dont see how thats the case cause normally once you remove the gas cap the system depressurizes. Good luck
