Ford F-350 Super Duty Fuel Tank

Easy Maintenance Tips for the Ford F-350 Super Duty Fuel Tank

The fuel tank is one of the more no-nonsense parts of the Ford F-350. As its name implies, it's a storage tank for the truck's fuel. But just like any other part in your truck, the fuel tank of the Ford F-350 is also prone to wear, corrosion, and damage, and once it starts to leak or gets foul, it will severely affect the performance of your vehicle.

Maintaining the fuel tank in your Ford F-350 Super Duty in good condition is not that hard. In fact, a lot of the things that would keep your truck in top shape you can do while on the road. In this guide, we'll list down some simple care and maintenance tips for the Ford F-350 Super Duty fuel tank:

  • Use only high-quality fuel.

While it does cost more, fuel sold from brand name gas stations is highly refined to remove the smallest impurities in the fuel. So while off-brand fuel may be cheaper, you also have a higher risk of fouling your gas tank with contaminants.

  • Don't refuel if the station is also replenishing its fuel stores.

Refilling the gas station's fuel reservoirs stirs up its dirt and deposits, which might be transferred over to your truck's fuel tank.

  • Keep the tank full as often as possible.

Or at the very least, avoid keeping the tank at low fuel levels. This is because the fuel also cools the various electronic devices mounted inside the tank, such as the fuel sensor and fuel pump, and very low fuel levels will cause these devices to overheat.

  • Replace the fuel filter regularly.

The fuel filter in your Super Duty helps catch any impurities from the fuel and will need replacement from time to time. Ideally, Ford F-350 Super Duty fuel filters should be replaced once every 15,000 miles, although you will need to replace the fuel filter earlier than that if you suspect the tank is contaminated or you are switching to a new tank.

  • If you're not going to use your truck for more than 2 weeks, add an anti-ethanol agent on the tank.

This will prevent the gas from jelling inside the tank, which might damage the fuel sensor and other devices inside.

  • Easy Tips on Installing the Ford F-350 Super Duty Fuel Tank

    Replacing the fuel tank in your Ford F-350 Super Duty due to leaks, fouling, or other types of damage ensures the continued safe operation of your pickup truck. But while any auto repair shop will be eager to install that new fuel tank for you, you can save a lot of money and time by installing it yourself. Unlike other parts of your truck, the Ford F-350 Super Duty fuel tank is quite easy to install as it is mainly held in place through several metal straps.

    In this guide, we list down some helpful tips you can use to install the fuel tank in the Ford F-350 Super Duty.

    Tip #1: Drain all of the fuel first.

    This is especially important if you are making the replacement due to a fouled tank. The old fuel may contain rust particles and other contaminants which it could bring over to the new tank. There are three different methods of draining the old tank – via the drain plug, siphoning through a filler pipe, and through the back of the tank—so make sure to choose one that you think is best in your case.

    Tip #2: Make sure the engine has cooled down to prevent burns.

    It should be cool to the touch before starting.

    Tip #3: Keep in mind that the tank will hold a flammable liquid.

    Work in a well ventilated area, disconnect the battery, and make sure any heaters, open flames, pilot lights, or electric devices that could start a spark are turned off.

    Tip #4: Take a picture of the fuel tank before taking out the fuel lines.

    This way, you’ll have an easy point of reference when installing the new tank on the underside of your truck.

    Tip #5: Be extra careful when handling the fuel sensor.

    The fuel sensor inside the fuel tank is quite fragile and can easily be damaged when being removed from the tank. Check the sensor as well for signs of wear or damage and replace it if necessary.

    Tip #6: Clean all the contact surfaces between the tank and the truck.

    All of the sides and edges where the fuel tank will be mounted should be free of rust and corrosion. If any metal panel or component is in need of repair, patching up, or replacing, do it before mounting the tank.
