I don't think you have to drop the tank to for a quick check of the hoses. I dropped mine to replace the rusted bolts and inspect the tank for any cracks or anything. If you remove the license plate holder and the black plastic holder for the filler hole you can get at the tubes and take a look.

Alternatively, there's a plastic plate behind the rear wheel well (covers the hollow area in the tube that has the hoses and the rear headlight wiring) you should be able to pop out the plastic rivets that hold it in place and yank it out. Then if you look straight up that area you have access to the tubes and a bit more space to work in.

There are a couple common issues that I know of. Check your rear body mounts. If they collapse it will allow the body to pinch the fuel lines and vent lines. The vent lines go into the rollover valve on the pass side behind the rear fender. It should be normally open and allow the vented fumes to go to the charcoal canister. The valve is notoriously bad and can break and pinch the vent lines ot break free and allow fumes into the vehicle.

I'm a newbie just got my first Jeep. Mine does this also not alot maybe half a second but it is the first vehicle I've owned that does this. Is this a common thing? I've also heard t can be negative or positive pressure (sucking or blowing) to tap your hand over it to determine. And a little o. Either side is okay? Which seems counter intuitive. So yeah some info would be appreciated!
