Tagged: 0 Thread(s). Quoted: 0 Post(s). The Prius gas tank is fitted with an internal bladder to prevent gas fumes from leaking into the air. It does create the problem of inconsistent gasoline fill-ups. 1 - The back pressure from the tank can cause early shutoff of the nossle. (don't overfill as gasoline can spurt out due to bladder pressure). 2 - In cold weather, the bladder gets stiff reducing the effective tank capacity. As was stated before the nominal tank capacity is 11.9 gallons.
Report Abuse. Hi, it's true all gen 2 Prius (current hatchback body style) hold a total of 11.9 gallons-however-You will never be able to get 11.9 gallons in a Prius, no matter what. Here's why: All Prius use gas as a coolant for the fuel pump.t s pretty rare for us to get even 9 gallons in the tank. Of course we don t let it go empty. The prius gas gauge has 10 bars. When you get to the lowest bar after some more gas is used it will start flashing.
