Having problems with your 2007 Volvo S40 2.4i Sedan ?

Gas pumps continuously cuts off during fill-up

\015 Every time I fill up my Volvo S40i at every station I've been to the pump will constantly cut off during fill-up. I've tried pulling the nozzle further out of the gas tank and pushed it in as far as possible (and yes moved the nozzle in every other possible direction, even turning the nozzle upside down), but the pumps still cut off and will never continuously fill the car. Any help?\015 Posted / edited by AnonymousUser on : 18-10-2021

\012I had a similar problem with my 1999 S80. Give this a try. You don't need any mechanical experience. At no point will you come into contact with any gasoline. This is a five minute fix if it's what I think it is.
Background: when you gas up your car, it goes down a tube to the gas tank. There is a vent on that tube to let off gas fume pressure that can build up in the tank. If the vent gets clogged pressure builds up in the tank. Modern gas pumps shut off when that pressure comes back up the tube from the tank. I think if you clean out the vent with a Q-tip you'll solve your problem. At least, it worked for me.
  1. Get a flashlight and some Q-tips (I suppose anything long and pokey will do).

  2. \012
  3. Go to where you put the gas in (you don't need to open to door or take the gas cap off).

  4. \012
  5. Crawl under the car behind the tire and look up with the flashlight to about where you'd put the gas in. You should see something like the picture below (taken from my 1999 S80). Note that at the end of the red arrow, you can look up inside the tube a bit? When I was having this problem I could only see what looked like white cotton inside the tube. It turns out it was an old spider's nest. The spider was long dead from the gas fumes, but his nest made it impossible for me to fill up my car!

  9. Place a Q-tip in the hole indicated by the red arrow. Swirl it around a bit. You shouldn't have to jam it or be very forceful. The Q-tip should remove any blockage.

    I suppose it's possible that when you open the blockage some gas fumes will vent out, so don't be smoking while you do this :) Now that I've said this, to be super-duper safe why not do this outside away from any chance of open flame.

  11. Go gas up your tank and see if it works. It did for me.

Good luck!
