Tank & Emissions Swap – Missing Connectors

Hi All,

2006 Gen II here. My car is from VT and is a rust bucket. I've slowly been swapping out crappy parts with good ones when the right one comes up.

Last week I bought a new tank with full emissions system attached for $150!!! Now here's the bad news.

In the service manual, it shows two ports in the section under the back seat. My old tank had three. Of course, this new tank has two.

My thinking was to swap out the wiring. When I set off to do that, I reached another impasse: power to the trap canister on the old wiring was an 8-port. This new tank has a 2-port.

So then I thought – why don't I then swap out the vacuum portion of the trap canister? Gave that a go, and was immediately halted by the size of it. Smaller on the new tank, bigger on this one.

I thought to myself: did I buy the wrong tank??? So I do some googling and some image searches on ebay as well, and every time I look up 2006 Prius gas tank, I get the same thing over and over. I checked the vin on my car, and yeah still a 2006!

Any light you can shine on this pickle would be greatly appreciated. I'm ready to take this darn thing to crusher.

 

I went to the salvage yard I like to frequent that specializes exclusively in Prius parts. This is what I learned. Both in fact are OEM, but it turns out 04 and 05 tanks were different from 06-09. I looked that up with a basic image search, and sure enough, it's correct. So the plan of action now is to rust primer the old tank, and transfer the emissions parts from the new tank onto the old one, while keeping the trap canister from the old one. Then I'll just sell the new one.

I'll show you some pictures. The first two are identical to my original tank. You see the trap canister in the second photo? The tank has a slope there to accommodate it's larger size. Look at the third photo. That's identical to what I bought. However, the vacuum on the trap canister for that tank is smaller, so no slope. I've also compared the parts of the emissions system, and saw the exact same Toyota-Denso part number on both. Life is bizarre huh?
