Does anybody else have this problem? Almost everytime that I fill up my FJ at the gas station, the automatic cut-off on the pump hose shuts off thinking that the tank is full, yet it seems to be caused by "back up" in the fill pipe to the tank. I can be empty and it still happens with the first squeeze of the pumps trigger.

Re: Gas tank backs up when filling, shutting off hose
I have seen the same issue, the nozzles click off at some stations, others do not. One thing that I have tried and had a bit of success with is pressing the nozzle real tight against the filler hole. The rush of air coming up the filler neck is what clicks off the nozzle, not the fuel. So, pressing in tighter seems so let the pressure equalize in the filler neck. Try it, maybe it will work for you.

if you are having problems filling the gas it could be a couple things. first the pumps at the gas station over fill at a fast speed, try slowing them down and try moving the hose back a little to give it some breathing space instead of shoving it all the way in the gas area. next is try a different gas station, believe it or not there is a difference.
like answer number 2 up there, California has a Fume Collector over the nozzle, and extends over the hose itself.... its really important NOT to "top it off" after the nozzle shuts off automatically.... it has a tendancy to fill up that vapor space with gas, and you can try to put gas in your car, but it stops each time you pull the "trigger" on the handle (acts like the tank is full) The service station person needs to come out and drain out the excess gas from the hose vapor space. (they are quite familiar with this.... it happens a lot)
The reason the gas station pump shuts off is when the fuel reaches the tip of the gas nozzle, so when you are filling your car and the gas nozzle (gas stations pipe) keeps shutting off it means that the pipe that runs to the gas tank is not open completely, what happens is when you pump the gas in the car the supply pipe from the gas tank opening to the tank fills up quickly and this causes the gas station pipe nozzle to shut off, have some body take down the gas tank and have a look at the gas tank opening and also gas supply pipe that runs from the gas filler opening ( on the car body) to the gas tank.

some prefer a name brand although I always fill up after 8 AM in the morning at my local station. The reason is the tanks are filled at 7AM at the station I go to giving me the satisfaction no moister from a very low underground tank will get into my gas tank when I fill up. All fuel tanks receive moister in their tanks. The tanks are electronicly read from inside the filling station. They have alarms that sound if too much moister is inside and shut the picticular tanks pump down. Some times they do not shut down for many reasons. One is a over ride switch incase that tank is the only one left with fuel in it especially on a holiday weekend. It has happened to me a few times causing my car to throw codes from the computer and also stalling out a few miles from the gas station after filling the vehicle up. That is why I choose to fill up mine after the station gets their fill up
the breather tube for the tank might be clogged not letting the air out. so when you fill the tank the fill cant get in fast enough b/c the air is not excaping. check the breather tube for kinks or bends. or even blockage of somekind
