Empty tank, but can only fill 1/2 the way

It's the fuel fill pipe. It's tight. Different gas stations (or different pumps at the same station) may be set to different sensitivity for the vaccuum-operated shut-off. Try another gas station. If it happens consistently take it to the dealer. In some early 2004's it was enough of an issue to have a TSB, and people who complained got a free replacement. Later units already had the improved fill pipe, but people still occasionally report this problem

 

yep. either be patient with the pump, or settle for half a tank. either way, you're still spending much less time at the gas station

good gas tank discussion going at this thread: http://priuschat.com/index.php?showtopic=1...ut+of+gas+after

I've had some success with not using the auto-shutoff and filling slowly.

 

Or if using auto pump - then only use the first click on the handle (the slowest speed).

 

That will do it.

I find myself going to an aging gas station with older, slower pumps.
