Prius Gas tank

try filling up on the slowest pump setting.
with the last pip flashing, in the summer you should get closer to 9+ gallons in.
also try fueling at a different station, not all pumps are equal.

if you're doing that, there might be a calibration problem that the dealer could look into. others here would know more about that than i would - i have seen threads on calibrating the fuel system - search...

removing the bladder would defeat the low emissions engineering in the fuel system.

hope this helps.

 

NO!!

If you don't like just putting 6 gallons in the tank get a Hummer.

Seriously, there is more to it than just changing the tank. Lots of electonic and enviromental issues.

 

combsad7,

your frustration is widely felt, and this question has come up before.

I wont even try to explain the byzantine nature of the fuel tank and
associated systems. [The key word is systems, which means great
complexity, and in the Prius, the liklihood that the computer(s) will start
throwing codes and shut the ICE down if it starts getting bad info as from an
attempted hack, work-around, bypass, etc.)

Go here and witness the wonder of the fuel system at first hand:

I suspect you'd need a new computer(s) and... a basketful of $$$.

The shorter answer is, "You can't get there from here."

 

You are most welcome. Glad that I could help.

I'm no expert, nor lawyer, but if this is a recurring condition, I would think fixing
a sticky fuel level sensor, or having the inclinometers re-calibrated would be covered
under warranty... it's a brand new car.
