Did notice some fluid on the gas tank skid but with the pray on the floor of the Jeep it looks like it was from the drive shaft, pinion seal and just flinging fluid all over. ?? Time for new drive shafts as well.

There's several posts here on how to track down and fix an evap leak. For me, it was the vacuum pump and seal on the canister. For others, it was the plastic line on top of the tank. I'm lazy, so below is a Google search that brings up a lot of reference.

And, yes, a smoke test is quick, but if it's a big enough crack, you'll see it.

Just had that issue a couple months ago. Replaced the o-ring, 3, on the evap canister, well the canister too since I was doing that anyway, and fixed.
