Corolla to Prius gas tank swap

Has anyone tried to swap a gas tank from a corolla, Matrix or Pontiac Vibe in place of the bladder tank. Physically the tanks look like they will bolt right in and I can get one for $22 at the local junk yard. I’m sure it will throw a code but as long as it runs and drives fine I’m ok with it. Just looking to go a longer distance between fill ups. I live in Florida and we are back in the 70’s and I had 2 ticks left on the gas gauge and it still stopped at 4.7 gallons and wouldn’t fill anymore.

 

I found that the race track near me has a pump that never acts up or clicks early and that’s the pump I always try to fill up at. I’m getting 250-290 miles out of a tank and it would be great to have a longer range between fill ups due to work.

 

I definitely have the mechanical know how just wondering if all the emissions from the Prius tank can be swapped to the corolla tank so no codes act up. All of the emissions stuff is on the outside of the tanks so it should work as far as I see.

 

No smog checks in Florida. I could literally throw a big Cummins diesel in my Prius and Florida could care less. The bladder is there to make your life hell lol. Actually it’s to keep less vapor in the tank for emissions purposes.

 

Well the bladder can’t be removed without literally cutting the tank open so that’s a no go. 9th gen Corolla, 1st gen matrix and 1st gen vibe. Some of the matrix’s and vibes were AWD and the tanks are 11.9 gallons on AWD and 13.2 gallons on FWD. physically the tank is a direct bolt in on the Prius it’s just swapping all the emissions stuff and getting it to work.

 

The black tank is the Prius tank and the silver is the corolla, matrix and vibe tank. The electrical plug for the sending unit is different and there are two extra holes on the corners on the Prius tank. Other than that that’s all I see different.

 

Corolla tank is top Prius is bottom. As far as the emissions goes the Prius definitely has a lot more going on and the corolla not as much. The Prius emissions definitely needs to stay and just incorporate it with the corolla tank.

 

I didn’t realize the Prius already had an access hole. Am interested to see if it lines up with the corolla fuel pump once installed

 

Thanks Mendel, this should help a lot!

 

Saw this post a few months back. Definitely helped in my decision to tackle this project. It looks pretty complicated but it’s just like any other gas tank just a rubber bladder and a temp sensor is really the only difference. The project is still a few months out but just gathering info for now.
