Monitored the fuel gauge on the dashboard of 2005, Toyota Prius in order to know when was running low on fuel. Has been keeping a log of fuel consumption, mpg and miles driven. Typically, ihe filled up the tank when the display showed only 2 or 3 bars remaining out of 10 bars when full. Based on the cars 11.9 gallon capacity each bar should indicate approximately 1.19 gallons of fuel. In the past it has taken 7-8 gallons to fill up the tank when the display got down to 2 or 3 bars. However, there have been several occasions where it has only taken 4.5 gallons to fill it up. Also there were 4 instances when attempting to fill tank up after the display showed 2 bars remaining, and it only allowed me to pump 3 gallons of fuel before the pump shut off. As much as I tried could not get any more fuel to go into the tank. When I started the car it only showed 6 bars on the display. I drove around the block and pulled into the service station again and attempted to put in more fuel. It only took about.2 of a gallon, but this time the display showed 10 bars. It seemed obvious that something was wrong with the fuel tank sensor system. A fuel gauge should provide an accurate indication of the number of gallons of fuel remaining.

The vehicle's gas needle indicated that the tank was half full. When the consumer attempted to refuel the vehicle, the pump shut off after only depositing 1.1 gallons of fuel into the tank. The consumer stopped a second time to try to fill the fuel tank and inserted the pump into the tank. After the attempt to fill the tank, the consumer removed the pump from the tank and fuel shot out of the tank all over the consumer. The fuel gauge still showed half of a tank. The consumer was told that the part needed would be a couple weeks and was forced to drive the vehicle. After driving the vehicle the consumer noticed that fuel gauge still in the same place. The dealer fixed the problem stating that water somehow got into the fuel cut off valve and caused the vehicle not to accept fuel. In driving home the consumer stopped again to get fuel and the same problem occurred.
