The under seat gas tank in my 1970 CJ has the sender on top and a drain on the bottom, so I'm guessing it's the correct one for this model, anyways it's just laying loose under the seat with nothing holding it. I found a few strap kits, but not sure which is the right one. I THINK I need one 2 piece strap kit, but am not sure. Can someone shed some light? Thanks!
