Gas pump stops before tank is full
 
The last couple times I filled up the pump stops before the tank is full. Tank is at 50-70% of the way. Should I keep pumping after it auto shuts or not.

Re: Gas pump stops before tank is full
 
I used to have the same problem on my G35 coupe. Sometimes it would only let me put 10 or 15$ of gas when i was on empty.

The problem was with the design of the fuel filler neck. Air pockets/vapours would get trapped and somehow the backflow prevention on the pump would get triggered. It was a TSB, but I bought the car when the warranty was already over, and I didnt want to pay to fix it. The solution on the TSB was to replace with a revised filler neck.

What i noticed was: 1) it only happened at shell and petro-canada gas stations. It didnt ever happen at esso. 2) if I only held the nozzle at 3/4 of the way, it would actually fill up and then stop when it was actually full.

No idea if this is any where near the same issue as I used to have, but it sounds the same and that is what I did to deal with it. I really hope that this doesnt become an issue with the jeep too. I havent had any issues yet, but I've only filled up twice.

If the tank isn't full ... Yes.

Sometimes it is just a matter of the angle of the nozzle. Try pulling it out a little or rotate it a little.

The first time I tried to put gas in my Overland, I couldn't get it to take more than a half tank. I even called the dealer to ask WTH.

I've decided that the nozzle has to go in a minimum distance and if you get one with a long coil on the spout that prevents this, you won't be able to fill it. I tried a different pump and there was no problem.

Our Prius does this with certain pumps as well. My solution? (Don't laugh!) Pull the nozzle out, turn it upside down, re-insert it and start again. For whatever reason, that seems to make it less sensitive to the back pressure. It still shuts off, but only when full.

Works for me in the Prius, not sure how it will work with the JGC, I don't own one yet. :-(

Thanks guys. Tried it at another more modern Mobil pump and it never stopped. Maybe the older pumps have more sensitive sensors

I've encountered this as well and pulling out the nozzle a little bit helps. It will still shut off when full just don't push the nozzle all the way in.
