Filed Dec 22, 2025 · Fuel system · TX

Having a hard time putting gas, I have to do it slowly so it can go in, the worst is when I put fuel a bit more fast it will throw gas out even if it ain't even close to half the tank.

When the fuel vents on the top of the fuel cell get old, they are extremally brittle. Washboard roads or a pot hole can jar the fuel tank breaking the connectors that go to the emissions system and the rollover valve. If any of these plastic pieces break, there is a chance for fueling problems and effects the drivability of the vehicle. The 3 connector vent is a non-serviceable part, requiring the gas tank to be replaced. The replacement has the same plastic connectors, leaving the possibility for breakage. These connectors breaking can lead to a multitude of issues, including but not limited to fuel spills while filling, leaking fuel from hoses. I have had 2 tanks in my 2012 jku have this issue and a quick search on jeep forums will show that this is not an isolated problem.

Engine Stalls Randomly while Driving. Will crank over several times and over approx 10-15 min. of cranking(Say every 3-5min) vehicle will and will restart. No check engine lights and no warning. The loss of power can be dangerous since brake and steering assist require engine to be running. Vehicle will be fine for several days local commute and problem will recur without warning, usually on longer commute. Vehicle is unsafe and unpredictable.

The skid plate assembly that retains the fuel tank is very corroded, corroded to the point of the fuel tank dropping out of the vehicle if not repaired as soon as possible. The other part of this issue is when trying to get this part, there is a backorder of approximately 50 of the skid plate assemblys! This information was provided to me by the Chrysler/ Dodge/ Ram /Jeep Dealership from where we purchased the vehicle new, and that has done all of the repair work on this vehicle since we bought it. The 2 things I find to be very concerning with this issue are the potential fire hazard if, and when a fuel tank were to fall out of the vehicle and the issue of a parts back order appears to show there is an ongoing issue with this very serious situation . Also this vehicle has never been used off-road or for any extreme off-road activities, solely on road use. I did contact Chrysler in regards to my concerns, but other than attempting to get the part shipped sooner, I was told the vehicle is out of warranty and there is no recall on it so there is nothing they can do.

Occasionally we would smell gasoline fumes. The occurrence became more frequent to the point we had a mechanic check it out. The mechanic dropped the gas tank and found that there is a steel ring between the tank and the fuel pump flange. This flange had rusted and expanded to the point of cracking the fuel pump flange. Mechanic replaced the flange, seal and fuel pump. I have retained the cracked fuel pump.
