Be careful that you get the correct size. The ones that Carpenter sells are too fat to fit properly. I found an o ring that was fuel resistant at the local Ace Hardware. Much petroleum jelly on the socket on the tank and none on the filler tube. Loosen the filler tube, remove the rubber gasket where the filler goes through the body and prepare to cuss a bit.

A lift is nice but not necessary as you can get to the tank from the wheel well with the tire and wheel removed.

Good luck.
