    My son's 2018 RT has been in storage in my garage for almost a year, due to a sudden health issue he suffered. When it was parked I treated the fuel (full tank) with fuel stabilizer. My concern is that the treated fuel is approaching a year old now and it looks like it's going to be stored for "a while" longer. Is there a way to drain the tank? I am assuming that it has an anti-siphon device to prevent simply siphoning the fuel out thru the filler neck. Of course, I could just drive it and use up the fuel but the tags are expired, and the insurance has been changed to a "fire and theft" policy, so probably not a good idea either for obvious reasons. Any suggestions??

    Fuel stabilizer, especially if you use a double dose, will allow the gas to last for 24 months. If you will be storing the car for longer than that, here is the Dodge service procedure for draining the tank:

    1. Remove the fuel pump relay from the PDC.
    2. Start the car and let it run until it stalls.
    3. Attempt to restart engine until it no longer starts.
    4. Turn car off, and reinstall fuel pump relay.
    5. With that finished, disconnect the fuel line from the fuel rail.
    6. Attach a hose to the fuel line and direct to a suitable storage tank for the gas.
    7. Using a diagnostic scan tool, activate the fuel pump and drain.

    yea, the tank is hard to get to as it is under/behind the back seat and it is a 2 section tank, or what they call a saddle tank.

    Thank you. Looks like I will need to get a scan tool.

    I hope you got it figured out! If not, try and empty the tank as much as possible first with a nice long drive
