Spring on one side only (driver's side I think). If you have the early type tank with sleeve that screws into the tank, the install will be a little easier. You will need to muscle it in--the tank sits on top of the frame rails. There are two fiber strips that go between the tank and the frame.

Shove the tank as far right as you can muscle it, push the left side up and then bring tank back left. The tank should fall right into position.
