In my Nissan Sentra 1.8, 2005 model car, when I go to gas station to fill gas, even after filling two to three liters of gas, the gas nozzle stops as if the gas tank is full. Sometimes while filling the gas, the gas overflows even if the gas tank is empty and can take 25 liters more in the tank. At the gas station when I open the gas tank lid to fill the gas, I listen a noise of air ( gas wapour) coming out of the tank. To fill my gas tank fully, the gas nozzle stops every two liters and to fill the gas tank fully this happens nearly 18 to 20 times. I can't fill my gas tank at a stroke. Thsi problem started since last 3 months. What should be the reason ? My mechanic says he has to take out the gas tank and repair it. Is this correct ? my email address is " [email protected] " Thanks. Janak Shah.

I have the same problem with my 2005 sentra. It is the vent control valve. The only cheap way to fix this would be to take it off and spray wd-40 and see if it works. You could also get the part form a junk yard. Nissanpartsdirect also has it. I beleive it is officially called the vapor canister.

Do you use only one gas station? Try another station / brand, it could be that the gas supplied to your station is off. I had a similar problem with my old Land Rover, then we found out that there was some illuminating paraffin in the gas. It didn't have a light to show a problem, but just didn't have power everytime I used a certain gas station. The dealer is now under investigation for diluting his gas to make some easy bucks.

I also have a 04 with a 1.8L. same problem. I took the fuel regulator off. It is a black box behind the rear tire under car. It only has 2 bolts to take off. After that there is a couple of vent hoses from the tank going to this box. Unplug them and 1 electrical connection. The electrical connection and one vent is connected to a T connection on the box that you can unplug by twisting on the T. Take that T off and look inside where you unplugged the hose on this T. There is a spring and a little plunger inside this tube. The plunger gets stuck. I took a little screw driver and some PB blaster and worked that plunger back and forth a couple dozen times and it unfroze. Put it back together gassed up just fine. I did not look but I was told regulator can be replaced for 200$. But a can of blaster is cheaper.

This is the same issues I'm having. Is there any answer to this?

SOURCE: When I go to gas station to fill the gas in my Nissan Sentra Car, (2005), even if the gas tank is almost empty, when I start filling the gas, just after filling 2 liters or so, the gas spills out and

the gas is spilling out from where? is it spilling out from the filler, where you are putting the gas in? also is the pump handle shutting of a lot?

If the answer is yes then it sounds like the vent is clogged, this is very common, the problem is one of two things, the evap vent valve is stuck closed or the most common is that there is a spiders nest blocking the vent hose hole, spiders climb into the end off the hose and make web nest and this blocks the hose. what is happening is the air is not coming out.

When you fuel up the tank, as the gas is entering the yank is pushes the air out through this hose to allow room for gas. in your case the air is not coming out and there is no room for fuel so it is like the tank is full which it is but with air not gas, you may need to go to shop and have is cleaned out or if you are a little handy with cars you will need to go under the car locate evap canister and follow hose off vent valve and clean it out. good day.
