What is this rear tank on this 1970 FJ40 (1 Viewer)

[FJ40 MATT]

I just picked this truck up today and there seems to be a factory rear tank inside the passenger rear corner wheel well with a shield around it. I’ve had a lot of FJ40’s since I was younger and never seen a tank like this. It looks factory bc it has a shield and factory mounting bolts. Just curious if anyone else know what it is. The tank is around the size of a gallon of water.

You didn't mention year...

My ‘70 had the same. It is emissions related. Vapor canister I believe.

Learn something new on these everyday.

Seems these were on some 70 and 71 models and on all 72s. Had a 71 I parted that had one. Dumped the tank and kept the skid plate. Picked up three more over the years. Idea is to use them to keep dirt our of the rear corners.

Always wondered why there were so many holes in that corner.
