SHORT ANSWER: Turn pump nozzle to 3 o'clock and pump away.... it won't stop til it's full.... then gas pump will click off automatically.... sweet fueling bliss..... Ahhhhh..... LONG ANSWER: I may have solved the refueling issue on GENII Prii, a problem of the AGES, the curse of the GEN II. ;-) I have 2 second generation (GENII) Priuses (or Prii), it is an issue on both cars. One car has 135,000+ miles and the other 275,000+ miles. I live in western NY, and this has been an unsolvable problem for me. I have tried calling dealerships, I have Googled my "googler" off looking for answers, with no success. I have not even found a clue. Big problem for me, more than most, because I commute almost 1000 miles a week. Both of my cars (2005 and 2005) have issues when refueling (for YEARS now). The problem is the pump constantly "clicks off" from the very start of the pumping process. I mean this baby clicks off a hundred or more times, it's relentless, infuriating, if not down right maddening. Any who, I have read on Prius Chat that many others have the same issue. This is a very annoying problem, as you well know if you are one of the lucky chosen ones. To make matters even worse, the problem would only get worse in colder weather. From what I have gathered it is caused mainly by the rubber gasoline bladder in the Prius gas tank. It somehow stops the pump from working properly, causing it to think the tank is full. Probably caused by the hole on the gas pump nozzle. (SEE PHOTO) (SEE LITTLE HOLE NOT THE BIG HOLE) SEE PHOTO of SMALL HOLE in pump nozzle, NEVER saw it before right: I think the way it works is when the small hole inside the nozzle gets covered it shuts the pump off (FULL TANK STATUS), this must be a vacuum trigger mechanism of some sorts. So when your pumping gas and the tank fills up the air hole in the nozzle eventually gets covered up and BANG off goes the pump automatically, preventing any potential over filling of the tank. Like others I have tried many different things to prevent this from happening. In fact I know most of you are saying to yourself, "that wouldn't happen to me. I am an expert." Not so. Guess what Charlie, this problem is no respecter of persons. In fairness though, this is actually my only complaint of the GEN II. With this small problem put to bed, I have no complaints. I absolutely love the GEN II Prius, I have saved THOUSANDS OF DOLLARS on my 190 mile daily commute. (95 miles each way at 65 mph averaging 44-47 MPH). It drives like a dream. I found this out when I had a loaner car last month. See my 2005 Prius needed an inspection, and I decided to replace the rear drums and shoes. They didn't really need it though. Anyways, the loaner was a 2 door Ford Fiesta. Driving this Ford Fiesta was no party. It drove like an M1 Abrams Tank. The worst car I have ever rode in. I was counting the minutes to get my Prius back. Back to the gas pumping dilemma. To solve this premature stopping, I have tried pumping very slowly. (Sometimes this technique will slightly help). I have tried pulling the pump out at different nozzle depths (Stopping every half inch or so). I have tried a myriad of other gas stations, and most pumps at those many different stations. I almost gave acupuncture and zen Buddhism a try. My Lord help me. One day for no reason at all, a Christmas miracle perhaps, I tried rotating the pump handle 90 degrees to the right. (3 o'clock). What are you KIDDING ME THE PUMP IS NOT STOPPING. I was counting the seconds, then at about 8.5 gallons, "CLICK", the pump stopped. I dropped to my knees. An angel choir could be heard. This technique, has worked for over 8 fill-ups now. I mean the tank fills up all the way, and only clicks off when completely filled. No jacking me around for half the day. Now if only I could find a way to keep the handle in that position so I could get in the car on freezing cold days while the pump is on. (I live in Upstate NY). This would completely solve the issue for me anyways. So again, try turning the gas pump handle to the 3 o'clock position while pumping. That is to your right rotated a quarter turn. Imagine the handle at the 3 o'clock position on a standard old fashion clock. I can't explain how this solves the problem other that to say, it must allow the gas to flow better down the neck of the gas tank into the inner gasoline bladder. If anyone knows why this might work, or the design of the neck of the gas tank. It might further give explanation to why this works so well. Unless somebody gives a better description of why it works, we will have to consider this an act of God. Please respond back with your test results. I think you will be surprised how it works, I certainly was. Merry Christmas. John Kinney UPDATE after about 1.5 years: Only have to turn the nozzle to the side if I am not paying attention now. See if I start filling the tank slowly for about 3 seconds. I can then gradually increase to full speed. But if I forget and quickly squeeze the handle really fast, then it may start this clicking off cycle (even with tank not filled.) That is when I have to turn the nozzle to the side (3 o'clock position) and pump for about 3 seconds. Then I can spin the handle down while continuing to pump. This has worked every time for 1.5 years. NOTE: For what it is worth. I also learned that the PRIUS with the bladder in the gas tank should never be over filled. I stopped doing this. Over filling can cause damage to the bladder. So when the gas pump clicks off after it's "full" do not force more gas into it. This is supposedly the safe thing to do.
